Advantages of a sole in ski boots?
The original soles are flat and not very rigid. They don't hug the bottom of the foot. As a result, support is limited and pressure distribution is poor. Pain in the malleoli and metatarsals can often be resolved with a specific insole. These also improve blood circulation and reduce cold feet.
The contribution of a specific sole in a ski boot should not be underestimated.
Special features of the 100
The 100 sole has a universal arch shape that is adapted to the majority of feet, unlike the 3Feet models, which offer 3 different arch shapes.
The 100 sole offers real advantages (support, comfort, warmth and distribution of support) compared to the original soles.
They are ideal for skiers from beginner to advanced level.
If you are looking for a perfect fit with your arch and more precision, you will have to switch to the 3 Feet model.
