A custom ankle brace system is disclosed which is constructed from a low temperature non-olefinic elastomeric blend material, and methods of fabricating and fitting the same. This material can be molded directly to a custom mold made from a casting of an affected body part. The final product will be an ankle brace that is able to be heated at low temperature (150° F.-200° F.) by use of an oven or equivalent, and custom molded directly on the patient. If necessary reheated, the ankle brace may be remolded to account for a change in the patients anatomy or for an increase in comfort.
