The RC5 Combi blends comfort, stability, and performance in a lightweight race fit boot. No matter the technique, the combi sole provides lateral stiffness for skating and forward flex for classic skiing. Grab the Easy Entry loops and pull the Speed Lock lacing for a quick and secure fit. Comfort Guard insulation and a breathable Triple-F membrane lace cover help keep feet warm and dry. The Triple-F Membrane keeps water and snow from entering boots, while allowing excess heat and moisture vapor to escape. The climate inside the boot stays warm and dry, no matter what the outside climate is. Inside the boot, a light, thin layer of water-repellent insulation material offers additional thermal protection in the forefoot and toe area to keep the skiers warm as they glide through the snow.
