Abstract
A ski boot consisting of an outer shell and an innerboot installed inside the outer shell. The outer shell is formed out of thermoplastic synthetic resin material mixed with a desired weight ratio of whisker. Mixing of whisker not only increases the flexural elasticity of thermoplastic synthetic resin material but also reduces the elastic distortion of the outer shell. Further, the abrasion-resistance of the outer shell is improved.
