Abstract
In composition of a copolymer making up a fitting pad for ski boots containing, as the major component, vinyl acetate, an acrylic component and ethylene, the content ratio of components other than ethylene is 20% or larger and the average molecular weight is 30,000 or smaller. The specified content ratio of the component other than ethylene and average molecular weight results in good fitness to a skier's foot thanks to good fluidization of the fitting material during application process, thereby assuring painless use even for a long period and good transmission of the movement of the skier's leg to the ski.
