Abstract
A customized fit shoe, and particularly a high-top ice hockey skate, having 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.
