SPORTSSKO MED TRYKKSATT ANKELKRAGE.

摘要

An athletic shoe formed of a sole, an upper attached to the sole and including an ankle portion extending around the medial and lateral malleoli, and an inflatable bladder attached within the ankle portion. The inflatable bladder has a medial section and a lateral section, with an inlet mechanism for supplying pressurized gas to the interior of the bladder. Weld lines divide the medial and lateral sections into upper and lower portions and prevent the formation of restrictive vertical columns of pressurized gas in the medial and lateral sections. One shoe embodiment herein is particularly adaptable in a high-top ice hockey skate and has a plurality of interior inflatable chambers. The chambers are configured and inflatable to different amounts to conform to the contours of the arch and the area below the malleoli of the foot in the shoe. The inflation of the chambers is accurately and easily adjusted through an upper push-to-deflate valve. When thereby adjusted, the concavities of the arch and ankle are filled without restricting the plantar or dorsi flexion of the foot.
