The Bugaboot has been an instant classic since it first hit the scene in 1993, and Columbia has updated the best seller with the addition of the exclusive Omni-Heat membrane. Like a space blanket for your feet, it reflects your own body heat back into the boot for lightweight warmth without the need for bulky insulation. The upper is constructed with durable Nubuck and split suede leather with rustproof speed hooks for a secure fit. Inside, comfort comes first with a contoured EVA footbed, lightweight molded midsole, and 200 grams of Thinsulate insulation. Road-hugging traction is provided by a non-marking, dual-density Omni-Grip outsole, which is designed specifically for the demands of winter weather.
