LaCrosse Footwear O-Therm Aerogel Insoles

Go the distance with the O-Therm Aerogel Footbed. The lightweight, insulating Aerogel traps micro-pockets of air without loft and continues to insulate when compressed, while the Ortholite open-cell PU foam footbed provides a secure fit with maximum comfort - a combination that provides more warmth underfoot and a more secure fit.
