A retaining strap 2 encircles the leg of the skier and keeps the tibia in contact with a support surface in the form of a padded cast 1, which is fixed to a deformable component 5 in the form of a leaf spring. The latter bears on the top of the boot 8, constituting a flexible connection to the front and a rigid connection to the sides. A cord 4 allows the spring 5 to be pretensioned towards the front. Straps 7 tightened by securing buckles 6 allow the deformable component 5 to be kept fixed to the boot 8. By means of the invention, the cross-country skier is able to use walking boots ideal for climbing, while at the same time being able to ski downhill supported by the tibias. |
