This was one of our key criteria during development of the ski~mojo and the answer is a simple yes. It has been described as "Bottom Cuddling".

All conditions are made more fun with the ski~mojo.

We hope keep the price affordable, about the same as a good pair of ski boots.

We do not think that the ski~mojo is expensive at all, relative to the overall costs of skiing.

£293 for say 10 weeks use, typical one week a year for ten years £29.30 per week,

Or

One week Ski Pass £145 (or more - not all resorts but certainly the main ones) get double the quality skiing in (case study of an independent test pilot) so do the amount of quality skiing that would have cost you £290 over two weeks for £145 in one week.

"Pays for itself in just two weeks skiing" after that skiing is "Half-Price" plus saves your knees (prevention is better than cure) and stops you spending a fortune at lunch-time and rest stops (because you're no longer tired and hungry and looking for excuses to delaying getting back on the slopes).

Only if they are in the same Power Level bracket (or higher).

You can adjust the Posture Strap with a Philips screwdriver, but you will need Boot spurs for bot sets of ski boots and probably different length rods.

As far as we are aware the suitability is not about age, but size and weight. Within the adjustable range we have yet to find an adult it does not fit. From 5' 0" to 6' 8" and from 50Kg to 150Kg. If it does not fit you then call us and we should be able to suggest simple modifications.

So anyone weighing at least 40Kg and at least 150cm (5ft) tall can use a ski~mojo

Yes, although the ski~mojo was specifically developed for skiers, by using the Soft-Boot Attachment (Optional Extra) it can also be used for snowboarding. The same issues about tucks and "Grabs" apply (See "The Downsides"), but for riding, it works equally as well for boarders as it does for skiers.

The ski~mojo has been designed to be non-restrictive to your movements and as such is not a knee brace. However, if you ever have problems with your knees the specialist will normally recommend that the best thing you can do is take some of the strain off the joints and will usually suggest losing weight. The ski~mojo takes up to 1/3rd of the strain off your knee joints and in many ways is better for your knees than most knee braces. However, if you have been advised to wear a knee brace we would not advise otherwise, just use the ski~mojo as well.

No, the power comes from the energy stored in the Power Units, which are special springs.

The ski~mojo attaches to your ski boot by way of a detachable universal joint. This requires the Boot Spur (ball stud) to be attached to your ski boot. It can be attached either by replacing an existing fitting, such as a power strap connecting bolt, or by making a 7mm hole in your ski boot.

Make the hole in the centreline of the back of your ski boots and the thread of the Boot Spur will "self-tap" into your ski boot. Tighten the square nut on the inside of the ski boot shell; if the Thread protrudes too far in, use an extra nut or washers to space it out (see fitting instructions).

Simply take the Boot Spur off your existing pair of ski boots and re-fit to your new ski boots as described in the fitting instructions. If you cannot fit the Boot Spurs at the same height as they were on your previous boots, fit them higher and cut your rods short by the appropriate amount. If you can only fit them lower than on your previous boots, contact us to get some longer Boot Rods.

A spanner &/or pliers
A Philips head screwdriver
Possibly a drill with 7mm bit, (depends on suitability of existing fittings)
Possibly a hacksaw and file (depends on the position of the fitted Boot Spur)

We have a temporary hook that can be used with hired boots. Please ask about this before ordering.

Within the adjustable range we have yet to find an adult it does not fit. From 5' 0" to 6' 8" and from 50Kg to 150Kg. If it does not fit you then call us and we should be able to suggest simple modifications.

No, the ski~mojo fits under all but tight fitting skiwear. As a guide if you can get a couple of medium-sized objects into your hip pockets e.g. phone, camera, wallet, you should be able to wear a ski~mojo under them. If not you may just have to wear slightly looser skiwear.

Currently the only place you can have your ski~mojo fitted is at our offices in Killamarsh, near Sheffield. We are in the process of signing up a number of fitters in other locations within Europe and details will appear in the Stockists/Agents section of the website.

The ski~mojo is incredibly strong and generally spreads the force from any fall over the whole length of your upper leg, actually reducing the effect of any impact. If the ski~mojo were to break, you would be grateful you had it on as the force required to break the ski~mojo is twice the force required to break your leg.

The power level is pre-set in the factory based on the weight of the skier.
If you need to change it, contact an authorised Agent or our office and we will arrange to change the power level for you.

The posture strap is detachable - push one arm back so that you have enough slack in the posture strap to enable you to un-hook the other end of the Posture Strap from the other arm.
It is advisable to take the posture strap off completely to avoid the risk of it dropping onto a wet floor.

Only if you're skiing in the incorrect posture or doing step turns, in which case the ski~mojo should help to improve your skiing style. The ski~mojo helps put you in the correct posture for skiing, which in turn, makes skiing less tiring.

The ski~mojo fits over most knee braces including carbon fibre ones.
You don't need to do the straps up tight, but this can lead to the ski~mojo slipping down when you don't have your ski boots on. See question "Can I walk normally while wearing it?"

Also the hinge of your knee brace and the pivot point of the ski~mojo may not be in alignment and could foul each other if the knee brace is particularly bulky. In this case, when fitting the ski~mojo, line up the pivot point with the hinge of the brace and cut rods to suit - they will probably be a bit longer than if fitted the "conventional" way.

With the ski~mojo switched off (walk-mode) and your ski boots on. You should be able to walk and sit as if the ski~mojo wasn't there.

As with the answer to "How do I sit down for lunch" - yes. However when you do not have the Boot-Rods on, you will find that either you can do the Shin Straps up tight enough that the ski~mojo will stay up as the shin straps are above the widest part of your calf or. you will find that the shin straps are level with or below the widest part of your calf and that you need to support the ski~mojo in some way. Our recommended method is to tie a piece of cord through the hole at the top of each ski~mojo arm and then once you have your ski pants on, tie this loosely to your sallopettes braces or the belt loops in your ski pants, once you have your ski boots on, undo the chord so it doesn't restrict your movements.

No, you wear the ski~mojo under your skiwear and simply switch it on when you put your skis on and switch it off when you take your skis off or when you ride a chair lift.

Yes providing that you are confident that it is not going to slip down. See answer to "Can I walk normally while wearing it".

There at two switches, one on the top of each ski~mojo arm. These are off (in walk-mode) when the switches are slid fully back and On (in ski-mode) when they are slid fully forward. These can be easily felt under your skiwear. To switch them on and off there must be no tension in the Power Cable. This means that you should have your legs straight. This can be done one at a time or both together either before or after you put your skis on or take them off. REMEMBER - BOTH switches must be either on or off. And BOTH must be FULLY slid Forwards or FULLY Slid Backwards.

“The ski~mojo “off-loads” weight from the legs and knees. The effect means that your knees only have to support part of your weight, not all of it. Our tests show that for our recommended Power Levels between 25 -33% of the strain is taken off the Knee Joints. So as far as your knees and thighs are concerned it feels like you’ve been on a very successful diet!

The first thing your Doctor or Surgeon will advise you to do is take as much strain off your knee joints as possible – this is what the ski~mojo will do for you.
One physician suggests that whilst rehabilitating from a knee or leg injury you may wish to make use of the ski~mojo’s power adjustment feature and initially set the power level higher than the recommended level. Then gradually reduce the power level over the course of your rehabilitation.

If you have injured or replacement knees, you should of course refer to your physician before skiing.
In the absence of sufficient statistical medical evidence, we cannot make any claims here. We do however have a significant number of testimonials from users who have knee injuries or have had knee replacements who are able to ski with the ski~mojo with little or no pain.

The general accepted view regarding the risk of knee injury is that “the more strain there is on the knee joint, the higher the risk of injury”. As the ski~mojo reduces the strain on the knee joint it would appear to be logical that it therefore reduces the risk of knee injury. We must however stress that at this time we do not have sufficient statistical evidence to corroborate this theory.

The ACL (Anterior Cruciate Ligament) injury is one of the most common skiing Injuries. This skiing injury is usually the result of a mechanism known as "Phantom Foot Fall". All ski injury statistics concur that the most common injuries are to the knee. Because of their mechanism ACL ruptures are not protected, even by a perfect ski binding. According to SITEMSH (Society International de Traumatology et Medicine Du Sports d'Hiver or The International Society of Ski Injury and Winter-Sports Medicine) 50% of all skiing injuries are knee injuries and 70% of those are as a result of Phantom Foot Fall.

One of the Organising Committee Members of SITEMSH, world leading Ski Physician and former professional skier, Dr. Marc-Herve Binet, believes that the ski~mojo could perhaps prevent the Phantom Foot mechanism for ACL Injuries. The phantom Foot Fall Injury occurs as a result of a number of combining factors; typically the skier will be falling backwards and into the slope with their weight on the downhill ski, their knee will be hyper flexed (typically the hips will be below the knees) and in this position the muscles around the knee joint typically relax, offering no support or resistance to movement. It is the tail of the ski that acts as the "Phantom Foot" or as a lever, which, with only the slightest of pressure, causes rotation of the unsupported hyper-flexed knee-joint. The result is a torn or ruptured ACL.

Dr. Binet's theory is that as the ski~mojo will not "relax" and as it is always trying to straighten the knee-joint, it should eliminate one of the crucial elements of the combination of factors that leads to the Phantom Foot Fall injury. The binding will not release during a Phantom Foot Fall Injury as the key element is that there is no resistance provide by the muscles around the knee joint. The ski~mojo will provide the resistance as it works to straighten the knee joint and will possibly provide enough resistant force for the binding to release.

Obviously research will need to be done to establish if this theory is correct in practice.

The ski~mojo “off weights” from the posture-strap to the shell of your ski boots, so also takes strain off your ankle joints and relieves the pressure on the soles of your feet (you effectively weigh less).

The ski~mojo has been specifically designed to mimic the way that a posture-chair or kneeling chair works. We do not have any conclusive medical evidence that this relieves back-ache or hip pain whilst skiing, but the theory has been endorsed by a number of doctors and seems to be backed up by significant anecdotal evidence from users.

The ski~mojo “off weights” from the legs and knees, taking significant strain off the thigh muscles when skiing – indeed this was the original purpose of the ski~mojo. Typically when skiing the thigh muscles do significantly more work than any of the other muscle groups in your body and it is the fatigue to these muscles that causes us not to ski as well towards the end of the day on the slopes. This muscle fatigue is a major contributory factor to a high number of skiing accidents. Even Professional skiers suffer from aching thigh muscles. Depending on the Power Level used, the ski~mojo does up to 33% of the work that your thighs need to do, effectively giving you a 50% power boost.
The BIG advantage here is the reduction or elimination of “Thigh-Burn”.
Thigh Burn occurs when we overwork our thigh muscles and they produce more lactic acid than they can cope with, this typically happens when our exercise moves from aerobic to anaerobic.
Some people say no pain – no gain, but by keeping your skiing just below the Aerobic/Anaerobic threshold, you can do significantly more skiing and more exercise overall. Similarly, your thigh Muscles will not waste away, indeed there is every chance that you will build them up even more with the ski~mojo than you would doing less skiing without it.

When we ski we often forget that we are at altitude and push ourselves to the limits of our physical abilities and over-exercise. We often push ourselves more than we realise and end up with our heart rate higher than recommended. When our Heart Rate is too high, we enter into the Anaerobic Zone, which also leads to the build up of Lactic acid in our muscles. Our muscles are trying to draw more oxygen from our blood than is available.
Using the ski~mojo our muscles need to do significantly less work, which makes it far more likely that our heart-rate will remain in the “Target Zone”.
With the ski~mojo you should be able to do more skiing – And rather than pushing your Heart Rate into the Anaerobic Zone, you should be able to do more “healthy” skiing in the “Target Zone”.

If you wish to do any grabs or high speed jumps(downhill) you will want to pull your feet uo, which is working against the ski~mojo. So, if you wish to do Jumps & Grabs, just switch the ski~mojo off before you do them, then switch it back on again afterwards always making sure that the switches are both either fully on of fully off.

The answer is a definite NO.
In fact you will probably build them up even more, as overall you will use them a lot more, just at a lower, safer work-level.

When we overwork our muscles they produce more Lactic Acid than they can cope with. It is this build up of Lactic Acid which causes "thigh burn" while skiing and stiff legs the next day. We overwork our thigh muscles in relation to the rest of our body when skiing, so it is usually the thigh muscles that limit the amount of skiing we can do. The rest of our body is up for more!

When you exercise you should try to keep your Heart Rate in the "Target Zone", 65%-85% of your maximum. Anything higher and you will be getting into the "Anaerobic Zone" which means you will be producing a lot of lactic acid in your muscles and you will tire very quickly. This is generally what happens when we ski.

Using the ski~mojo reduces the work that your thigh muscles have to do by up to 30% and this is usually more than enough to keep you out of the "Anaerobic Zone" and in the "Target Zone". As a result you can ski longer and harder which increases your heart rate (within the Target Zone) which burns more calories thus helping burn fat faster and helping the heart to become fitter. Also, your knee cartilage and ligaments take a pounding when skiing. The ski~mojo acts as shock-absorbers, taking up to 30% of the strain off and therefore protecting the joints.

ski~mojo turns your skiing day in to an all-round work out!

It's probably easier to answer why wouldn't you want it.

1. You have to pay for it although we believe it pays for itself in two weeks skiing
2. It adds a small amount of bulk to your legs that you may not be able to fit under your current skiwear.

It is NOT recommended but yes you can. However there is more chance of the switches getting knocked accidentally and it can catch on chairlifts etc.

If you do wear it outside we suggest a bit of cord (preferably elastic) is used to connect the two ends of the Posture Strap, across your front.

Yes, you can re-adjust the posture strap length and height at any time in the same way as you would set it up from the fitting instructions. However, you can't lengthen the boot rods, as once cut they cannot be made longer. If you need to have longer rods please call us.

If it breaks as a result of impact, you'll probably just be grateful you had it on as it would take twice the force to break the ski mojo that it would take to break your leg.

In the unlikely event that it broke as a result of mechanical failure or faulty components, there is a full Warranty to cover replacement and repair within the first year.
