Maxed out on warmth and protection, the Bugaboot Max Electric represents our most advanced, technical offering for cold-weather boots. Bearing the iconic Bugaboot name, it delivers classic Columbia performance in a maxed out package that utilizes all of our most advanced technologies - including battery-powered heat on demand - to keep feet happy, warm and dry even in the worst weather you can dream up.The clean, modern design keeps the look sleek and streamlined while 200 grams of insulation combines with Omni-Heat thermal reflective technology to lock in body heat for serious warmth. When body heat is not enough, turn to push-button electric warmth and power up the built-in rechargeable batteries that provide three temperature settings for maximum protection from the cold. On the low setting, heating pads located under the ball of the foot deliver warmth for 4 hours; on high, expect 2 hours of heat where your foot needs it most. Outside, waterproof synthetic leather with sturdy overlays create a rugged frame and waterproof laces with metal lace hooks lock your foot down for maximum stability. The oversized Techlite heel shell is both lightweight and super stable, and a strategically-placed TPU shank in the midsole provides even greater cushioning and support. Sticky rubber soles will keep you glued to the ground even in snowy, icy environments.
