Abstract
Ski boots and other cold weather articles are described made from polymer compositions that are exceptionally stable at low temperatures. The polymer composition, for instance, may contain a thermoplastic polymer, a thermoplastic elastomer, and an impact modifier. In one embodiment, each of the individual components are selected such that they do not undergo a second order transition within a temperature range of from about 50° C. to about −40° C., and particularly from about 23° C. to about −40° C. In one embodiment, the polymer compositions are used to mold the outer shell of a snow ski boot.
