Frequently Asked Questions

 

Why should I test the Ski~Mojo ?

Almost certainly, this is what the Ski~Mojo is best at. It will benefit you in two main ways:

Firstly, on our recommended settings, the Ski~Mojo will reduce the load your knees have to endure by around 33% thus reducing the stress your knees are subjected to. This will allow you to be more in control of your skis, reducing the risk of further injury and reducing or eliminating any pain or discomfort that you may normally be accustom to.

Secondly, the Ski~Mojo is a shock absorbing suspension system. Normally when skiing you have constant “chatter” going through your knees which can cause irritation and subsequent swelling of the knee. The Ski~Mojo absorbs this chatter and any compressions.

Almost certainly, as normally when skiing you get constant “chatter” going through your whole body; as the Ski~Mojo is a shock absorbing suspension system it reduces the stress and vibration/jolting that your back and hips have to endure.

The Ski~Mojo also supports you in a good posture as it mimics an ergonomical (or kneeling) chair, which also takes strain from the back.

Like the electrically assisted bicycle, the Ski~Mojo has also convinced many skiers who do not suffer from any pathology. They use the Ski~Mojo to improve their performance (and in particular their muscular endurance) during long days of skiing. It allows the skier to maintain an optimal technique and curve control even after numerous runs, and thus to enjoy skiing tenfold.

The Ski~Mojo is also used by some athletes for training as well as some ski schools to help skiers to correct certain technical postures.

Last but not least, by delaying muscular fatigue, the Ski~Mojo reduces the risk of falling and therefore improves your safety.

Note that the Ski~Mojo is already used by many mountain professionals (instructors, ski patrols, …).

Walking is a movement that is difficult to reproduce in a purely mechanical way. The Ski~Mojo was designed for skiing or snowboarding (as its name suggests). This movement is relatively simple since it just involves bending the knees when the feet are in contact with the ground. For walking, it is quite different. Walking with the Ski~Mojo activated/engaged will be more difficult and in this situation the user can deactivate/disengage it very easily.

The Ski~Mojo also requires a rigid support point on the shoe and walking with ski boots

Many Ski~Mojo users also use it for ski touring; but on the way down! Indeed, to go up, it will not disturb you but we will not help you either.

For the ascent, two solutions are available to you:

  • Either have it installed on your legs, but deactivated/disengaged. It will be quickly forgotten and you can even make your conversions quite normally.
  • Or in the backpack (1.4 kg without the harness, plus 0.150 kg for the harness that you can keep on you). It will then take you less than two minutes to install it once you reach the summit.

In both cases, the Ski~Mojo will give you a lot of pleasure and comfort on the way down.

To convince you, or for more explanation, you can watch this video on youtube (in French).

The Ski~Mojo was tested by the scientific department of the French Ski Federation. As this exoskeleton is considered to be “ergogenic” (which improves muscular performance), it is prohibited in competitions in the same way as “unnatural and artificial means which modify the performance of the competitor and/or represent a technical correction of individual bodily capacities whose performance is insufficient” (Article 222.5 of the FIS regulations).

When skiing with the Ski~Mojo :

Yes – in a positive way!

The Ski~Mojo will work with your natural articulation when skiing and it will help you to maintain the correct posture , also as it takes less physical effort to ski, it is easier and you can ski for longer, all factors which help you to improve your skiing technique.

The Ski~Mojo takes on 1/3 of your weight. This means that your legs have 15 to 30 kg less weight to carry and this requires a short acclimatisation phase which rarely lasts more than two runs.

This is why we encourage you to try the Ski~Mojo on longer runs. The beginning of the first run will feel strange but you will feel better by the end. The second run will be the one where you get your bearings back.

No the ski~mojo is one-size-fits-all. It has telescopic adjustments to fit your leg size. The Posture-Strap and Knee-Supports have Velcro adjustment so you easily adjust it to the correct setting for you.

The only choice that you need to make is which spring strength to select. There are three standard strength springs. The strength you select relates to your weight.

  • Gold springs are suitable for skiers weighing 75Kg to 120Kg
  • Silver springs are suitable for skiers weighing 55Kg to 85 Kg.
  • Silver springs are suitable for skiers weighing 38Kg to 62 Kg.

As you can see, there are overlapping areas and some people may have a choice between two models. In order to make your selection, choose the model that allows you to be as far away as possible from a minimum or maximum setting.

To help you in your choice, you can consult the table available by clicking here.

Many people find that using the Ski~Mojo removes the need to wear a knee support or knee brace. However if you do need to wear a knee brace (if it has been prescribed), then the Ski~Mojo should fit easily over any knee brace.

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 around 33% 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 and offering skiing injury prevention.

Ski~Mojo turns your skiing day in to an all-round work out!

Falling while wearing the Ski~Mojo is usually no different than if you fell without one. As the Ski~Mojo runs down the side of your leg it works as side impact protection bars, just like those on a car and will often reduce the affect of any impact. However, under certain circumstances: e.g. if you fall on the end of the upper telescopic rod, it may cause bruising (in the same way as if you fell on your keys if you had them in your pocket. There is a layer of Neoprene between your leg and the rod, which can usually be folded over and “doubled-up”; you may wish to add additional padding to fit between these rods and your legs to further help reduce the risk of bruising.

If you fall or are hit by another skier/boarder from the side then the Ski~Mojo will take the majority of the impact rather than your leg. It will spread the impact down the length of the Ski~Mojo which has the effect of cushioning any impact you receive. If you were not wearing the Ski~Mojo, then any impact would be felt directly on the side of your leg.

We cannot make any claims that the Ski~Mojo is impact safety equipment. The above is based on the anecdotal evidence of several Ski~Mojo users. The most relevant anecdotal evidence is that we have not heard of a single injury (other than normal bumps and bruises) sustained by a Ski~Mojo user other than in circumstances where they fell that the injury would have been worse if they had not been wearing their Ski~Mojo.

Is the Ski~Mojo easy to use ?

The initial fitting should take no longer than a few minutes, only one tool is required and that is a small Allen key that is supplied with the kit.

After that it will take very little time to put on and take off each day you ski. Simply put it on in your room before you put on your ski trousers (see fitting instructions for how to do this) then pull your ski trousers over the top and head down to the boot room to put on your ski boots. Once your ski boots are on then it’s a simple case of connecting the ski~mojos to the attachments on your ski boots.

The only tool that is required is a small Allen Key that you receive with the kit. adjust to the spring tension to suit your weight.

The Ski~Mojo fits into almost any alpine or touring ski boot. It is attached to the boot by means of “boot connectors”. The Ski~Mojo is delivered with two pairs of connectors:

  • Temporary connectors (clamps): these are placed on the top of the boot shell and do not require any other tools than those available in the kit. They are mainly used when testing the Ski~Mojo. If you are using rental boots, these connectors should also be used.
  • Permanent connectors: These are usually installed by the vendor.

Snowboarders will need special attachments which are available on our website (under Shop/Accessories) or from most of our dealers.

The total weight of the whole kit is 1.6 Kg.
What needs to be considered is the fact that when you are skiing the Ski~Mojo is supporting some of your weight rather than you carrying its weight.

Both solutions are possible:

A large half of the users wear their Ski~Mojo completely invisibly under their ski trousers (loose fitting trousers are fine).

Another half of the users wear their Ski~Mojo over their trousers, visibly. Be however careful as this can lead to certain risks:

  • Although to our knowledge this has never happened, it is possible that the harness can get caught on the chairlift with the consequences that this can have when disembarking.
  • You will not be able to cover your shoes with your trousers.
  • If snow enters the mechanism and compacts and/or freezes there is a high risk of damaging the system.

Undo the buckles on the elastic groin straps and disconnect the poppers on the top of the telescopic rods by pulling on the webbing tags: Then lift the Webbing Loops off the telescopic rods which will enable you to Lower the Posture-Strap.

Reverse the procedure to re-attach when ready.

There is no need to take special care when removing your Ski~Mojo: dry it before storing it and fold the velcro back on itself to prolong its life.

However, the Ski~Mojo has some wear parts and we recommend that you send it back for service after 70-90 days of use. More information at www.Ski~Mojo.ski/en/revision

Problem solving :

The Ski~Mojo is an exoskeleton. Just as your skeleton is connected to the ground through your feet, the exoskeleton needs to be connected to the ground (through your shoes). So you can’t really say that this is a defect, as it is the very design of the exoskeleton that requires this connection to the shoe.

This is why we have developed special suspenders for those who need to wear their Ski~Mojo without their boots on. You can find them in our online shop or at our dealers.

All the components of the Ski~Mojo can be exchanged/replaced at all our dealers. The repair or exchange of the broken part is covered during the warranty period, provided that you can prove that your Ski~Mojo is still under warranty (purchase invoice to be kept).

If you have any problems, please contact us by email or telephone and we will find a solution that will allow you to ski again with your Ski~Mojo as soon as possible.

In the unlikely event that your Ski~Mojo fails, there is a full warranty to cover replacement and repair within the twi first years. Keep your invoice.

In reality (other than general wear and tear) we may repair any faulty part irrespective of the date of purchase.
