Abstract
The shoe consists of a shell (1) made of synthetic plastics material and has a bellows-like corrugation on the surface of the shell (1) in the area (2) of the roots of the toes. Ridges (3) and furrows (4) extending transversely to the longitudinal direction are provided, which, when viewed from above, are seen to be arranged asymmetrically and run backward towards the outside (10) of the foot. (FIG. 3).
Claims2
A shoe, boot or hiking boot comprising a shell of selected thickness constructed of elastomeric material, said shell being corrugated in a bellows like construction in the region of said shell corresponding to the roots of a users toes when said shoe, boot or hiking boot is worn, said corrugations being made up of ridges (3) and furrows (4) extending in a direction substantially transverse to the longitudinal axis of said shell, and when seen from the top of said shell, arranged asymmetrically and running obliquely backward towards the lateral portion (10) of the foot in an arch with the apex thereof directed toward the front of said shell, each ridge (3) on the outside of said shell lying opposite a furrow (7) on the inside of said shell, and each furrow (4) on the outside lying opposite a ridge (8) on the inside, the base of the furrows (4) on the outside and the base of the furrows (4) on the inside lying in approximately the same geometric enveloping surface equidistant to the surface of the shell, and the depth of the furrows (4) in the area of the side walls of said shell decreasing progressively as compared to the depth of the furrows in the top of said shell with the thickness of the shell in the region of said ridges (3) and furrows (4) being less than the thickness of the remaining portion of the shell.
