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.
An inflatable bladder and valve assembly for providing a customized fit for an athletic shoe is also disclosed herein. A shoe bladder having a plurality of compartments, which are air pressure adjustable through a bladder opening, is fitted into a shoe to individually fit the shoe to the foot. A finger tip actuable valve assembly is connected to the shoe bladder and communicates with the bladder opening. The valve assembly includes a valve housing, a valve seat disposed in the housing and having a conical-shaped seat area, a valve body and a biasing spring. The valve body has an inner portion having a flat surface and the biasing spring biases this inner portion against the valve seat such that the flat area mates against the conical-shaped seat area to hold the valve assembly in its normal closed position. The outer portion of the valve body can be depressed to open the valve and allow air to pass therethrough to inflate or deflate the bladder compartments as needed to provide a custom fit. It can be depressed by a finger tip or when a separable hand pump is attached thereto to open up the bladder opening so that air can be pumped into the compartments.
