The KLIM Force GTX BOA Boot is built for riders who know cold feet can ruin a ride faster than bad trail conditions and an empty fuel tank combined. Designed specifically for trail riders demanding maximum warmth without sacrificing walking comfort, the Force combines premium insulation, waterproof protection, and all-day support for brutal winter conditions. GORE-TEX® construction keeps feet dry while 1000 grams of 3M™ Thinsulate™ insulation and an insulated aerogel Ortholite® O-Therm™ insole deliver serious warmth for the coldest days on the trail. The BOA® Fit System provides quick, precise adjustment while the custom MICHELIN® outsole improves traction on icy surfaces and staging areas. Warm, supportive, and built for long winter miles, the Force GTX BOA Boot is basically designed for riders who still say "it's not that cold out" while their sled is making noises that sound personally offended by the temperature.
