This is the sole length of your boots in millimeter.
It is NOT your shoes size or mondo point!
On ISO conform skiboots you find the sole length written on the shell, close to the sole. Most boots have it on the side of the heel piece. This is an important information because skiboots with the same shoe size can have a different sole length, even when they are a different model from the same manufacturer.
Our standard spacing for the bindings is 120mm. On request we can do a wider or a more narrow spacing. This depends on your boots and also personal preferences.
Please verify with your ski boots if the requested stance is possible:
To do this you close the buckles of your boots like you do it when you go riding. Then you place them parallel together on a flat surface, so the shoes are barely touching each other (allow some mm space). Now you can measure the required binding distance. Verify that the distance is the same on toes and heels!
You should not only check the distance on the ankle, also on the top shaft. Some boots are wider on top, so if you put them too close together the shafts press them outwards and you end up standing with open knees and fighting your equipment.
On most boots you find a fine casting line on the shell, which is the center. If you dont have it or you cannot see it anymore, measure and draw a marking line in the middle of the toe and heel pieces.
One key to monoski is to have your knees always tucked together. This helps you to control your ski better and also avoids broken bindings, damaged shoes and ripout of screws. It is a natural behaviour to spread your legs if you are loosing balance, so be patient and try to focus on improving your riding style before using a monobelt or trying the following trick. It will make you a better rider.
If you still have problems to get your knees together there is the above mentioned trick which helps some riders. The bindings can be mounted in a slightly V position, this means the front toes have less spacing (some mm) then the rear toes. If you bend your knees they will go together more easily. Please try this on an old monoski first, for some it works like a miracle, others do not like this stance at all. We do not recommend to mount bindings like that if you have never tried it before!
