Patent

CA 2466739

An article of footwear (100, 300) is disclosed having an upper (110), a foot- supporting member (200), and a sole structure (120). The foot-supporting member includes a heel region (102) located at a greater elevation than a forefoot region (106), thereby defining a recess under the heel region. The sole structure (120) includes a midsole (130) that forms a protrusion on the interior of the footwear. The protrusion mates with the recess to provide support for the heel region. The foot-supporting member may also incorporate pronation control characteristics, including a downward cant from a medial to a lateral side of the foot-supporting member and a region of reduced support generally underlying the first metatarsal. To further reduce the rate of pronation, the sole structure includes a region in the rear-lateral corner that is more compressible than other areas of the sole structure.

L'~l~ment de support de pied comporte une zone de talon sur~lev~e par rapport ~ une zone d'avant-pied, d'oÕ la formation d'un ~videment sous la zone de talon.
