SOLE AND SHOE FOR CROSS-COUNTRY SKIS OR TELEMARK STYLE SKIING Russian patent published in 2010 - IPC A43B5/04 A43B13/14 

FIELD: personal use articles.

SUBSTANCE: sole of shoe for cross-country skis or telemark style skiing consists of back part, which comprises shoe heel (13) and front part (12), having slightly cup-like shape. Sole (10) is wholly made of comparatively rigid material, preferably, plastic, and on the side of bottom in the area of front part (12) and/or in the area of back part (11) it is equipped with a layer (14) of protector from comparatively soft, preferably, rubber-like material. To improve bend elasticity, thickness of front part (12), which is on top fixed to shoe in the form of external layer, at least in the area of metatarsophalangeal section M is considerably reduced compared to other parts of sole (10), in particular compared to area (30) adjacent to metatarsophalangeal section M and diverging towards back edge of sole (10). Thickness of area (30) continuously increases, starting from metatarsophalangeal section (M) and stretching in direction of front part. As a result, elasticity of bend around axis, which is mostly transverse to longitudinal direction of sole (10) on metatarsophalangeal section M, achieves maximum value. Using sole of the invention, ski shoes were made with such a sole.

EFFECT: consists in the fact that relatively high longitudinal bend elasticity is achieved with preservation of proper side stability and simplicity of manufacturing.
