Named after the term for frost formed on cold objects by rapid freezing of water vapor, our women&';s snowmobiling boots are tough enough to stand through any weather. You can style the Rime women&';s insulated snow boot to your liking with the four different shoe lace colors provided with each pair. The 3M Thinsulate insulation is at an ideal weight of 800 grams for warmth while on the trail. Your coziness level will be 100% because of the faux fur soft lining throughout the interior of this women&';s insulated snowmobile boot! The toe cap gives you extra wear protection and the out sole has excellent traction for walking on snow and ice.
