Legendary Head brand Operator boots are designed for extreme cold, outdoor activities. Although listed as snowboard potential, they are more flexible than true snowboard boots, which means they are comfortable to walk in. If you work or recreate outside, these boots are rated to -40 degrees, the same as Sorels. The BOA lace system is super-quick and easy: Enter foot in boot, push in knob, turn to tighten as you wish. To release, simply pull button out and the boot instantly relaxes for removal. No laces to thread and tighten and no pulling laces to untighten. Boots are rated waterproof and liners are easily removed for drying.
