Aerotherm insoles provide a serious thermal barrier which traps warmth and blocks cold from snow, ice, or freezing concrete floors.
High-tech aerogel insulation between aerotherm foam insulation and a wicking top fabric provide amazing thermal protection. When you put these insoles in your shoes or boots they provide a thermal barrier that immediately traps warmth and prevents cold from seeping in.
Aerosole insoles come in 5 sizes and can be trimmed to fit.
