The Sorel ThermoPlus Extreme Innerboot is made specifically for the Alpha Trac Lace and Alpha Trac Buckle boots. Sorel’s most advanced liner with its anatomical fit, provides excellent fit and comfort. Radiantex Thermal reflective membrane provides a solid barrier for protection from the cold and heat retention and a protective outsole provides traction so liner can be used alone as an indoor slipper.
