Abstract

A method of making a skate boot upper, including integrally molding a boot portion from a first material, the boot portion including at least an instep portion and at least part of a tendon guard, manufacturing two quarters of a second material more rigid than the first material, and assembling the upper by attaching edges of the quarters to the boot portion with the quarter overlapping the boot portion only along said edges. Also, a method of making a skate boot upper, including manufacturing a boot portion from a first material, the boot portion including at least an instep portion and at least part of a tendon guard, manufacturing two quarters of a second material more rigid than the first material, and assembling the upper by attaching edges of the quarters to the boot portion through stitching, adhesive or lamination.

Claims

1. A skate boot for receiving a wearer'"'"'s foot and ankle therein, the boot comprising:

a boot upper fixed to an outsole, the boot upper including;

first and second quarters, each quarter having a bottom section for covering a respective side of the foot and a top section extending from the bottom section at a rear thereof to cover a respective side of the ankle,

a vamp for covering a front portion of the foot and connected to the quarters,

an instep portion connected to the vamp and quarters for at least partly covering a top portion of the foot, and

a rear portion connected to the quarters for covering a rear portion of the foot and ankle;

wherein at least the instep portion is made of a first material;

wherein the first and second quarters are made of a second material, the second material being more rigid than the first material, at least a major part of the instep portion being free of the second material; and

wherein the first and second quarters are connected to the vamp, the instep portion and the rear portion through stitching, adhesive or lamination.

2. The skate boot according to claim 1, wherein at least an upper part of the rear portion is also made of the first material.
