Caffrey Subzero Insole

Caffrey Subzero Insole is a low-profile thermal insole for winter boots and shoes. Its construction combines a soft felt top layer with an aluminum base layer that reflects body heat, helping retain warmth while providing a cushioned feel.

It fits sneakers, dress shoes, and work shoes in addition to winter boots. Fused foil-and-felt construction supports everyday winter use.
