Abstract
The invention relates to an outsole for a cross-country ski boot or telemark boot, consisting of a rear portion 11, which comprises a shoe heel 13, and a front portion 12, which is of slightly dish-shaped configuration, the outsole 10 being produced so as to be continuously of relatively hard material, especially plastics, and being provided on the tread side, in the region of the front portion 12 and/or in the region of the rear portion 11, with a tread layer 14 of relatively soft, especially rubber-like, material. An improvement of the bending flexibility is obtained in that the thickness d of the front portion 12 which is to be attached to the upper of the boot in a skin-like manner, at least in the region of the metatarsophalangeal zone M is significantly reduced relative to the remaining region of the outsole 10, especially relative to a region 30 adjacent to the metatarsophalangeal zone M which extends towards the rear of the outsole 10 such that the bending elasticity, about an axis substantially transverse to the longitudinal direction of the outsole 10 in the metatarsophalangeal zone M, is at a maximum.
