Patent

CA 2493591

A sport boot (20) is provided that is suitable for, but not limited to, use as a snowboard boot. The sport boot (20) includes an outer shell (22) and an inner liner (24) received within the outer shell (22). The outer shell (22) includes an outsole (26) and a protective upper (28) affixed to the outsole (26). The inner liner (24) includes a cushioning midsole (48) and a flexible upper (50) affixed to the midsole (48). Unlike conventional sport boots that place the midsole between an insole board and a shank on the outer shell, the present invention incorporates the midsole (48) onto the inner liner (24) directly under a rider's foot to provide a level and more stable platform. With the midsole (48) built into the inner liner (24), there is an improved relationship between the horizontal plane a rider's foot lies in and the horizontal plane of the midsole (48). When attached in this manner, a rider's foot and the midsole (48) more effectively remain in parallel planes, which improves the overall comfort and performance of sport boot (20).

L'invention concerne une botte matelassée pour le sport (20) qui convient, mais pas exclusivement, comme chaussure de planche à neige. La botte matelassée pour le sport (20) comprend une coquille extérieure (22) et un revêtement intérieur (24) logé dans la coquille extérieure (22). La coquille extérieure (22) comprend une semelle d'usure (26) et une tige de protection (28) fixée à la semelle d'usure (26). Le revêtement intérieur (24) comprend une semelle intercalaire de rembourrage (48) et une tige souple (50) fixée à la semelle intercalaire (48). A la différence des bottes matelassées pour le sport classiques, dont la semelle intercalaire est placée entre une semelle intérieure et un cambrion sur la coquille extérieure, la chaussure de l'invention intègre la semelle intercalaire (48) au revêtement intérieur (24), directement sous le pied de l'usager pour assurer une plate-forme plane et plus stable. La semelle intercalaire (48) étant intégrée au revêtement intérieur (24), une relation améliorée est créée entre le plan horizontal sur lequel repose le pied de l'usager et le plan horizontal de la semelle intercalaire (48). Ainsi associés, le pied de l'usager et la semelle intercalaire (48) restent plus efficacement en plans parallèles, ce qui améliore le confort général et la performance de la botte matelassée pour le sport (20).
