The heart of the Blaze is an internal, moisture-wicking mountain bike shoe that's fully insulated with a channeled, high-loft Primaloft synthetic sheath featuring 10,000 W/P + 10,000 GM2 wind- and waterproof performance plus a heat-reflecting insole and protective reinforcement in key wear zones. The result is a breakthrough in warm, dry comfort with purpose-driven details that inspire confidence to pedal through the toughest winter riding conditions.
