A waterproof winter boot with a felted-wool shaft is warmed by 200gm Thinsulate⢠insulation and temperature-rated to -30°C / -22°F to help you stay dry and toasty warm on the chilliest of days. The removable, contoured EVA insole cradles and supports your foot, and mixed treads and lugs deliver excellent traction on wet and icy surfaces. A full-length side zip closure makes it easy to get on and off, quick-adjusting laces provide a fit that feels custom and comfortable, and fuzzy fleece lining feels soft and cozy against your skin.
