ABSTRACT:
The invention provides ice skates and methods of making ice skates which have a body of a synthetic plastic material and a steel blade. The body includes an upper portion for attachment to the sole of a suitable boot and the blade has an upper portion enclosed in the body and a lower portion projecting from the body. The blade has a non-interfering upper surface which allows the body to move freely longitudinally of the blade during shrinking. This movement prevents build-up of residual stress in the body.
