Designed to wear inside any style boot, our new split-toe 1mm Neoprene Heat Booster Socks boost warmth by 5-10 degrees F. Bottom line: longer sessions in frigid water, where you can focus on performing, rather than freezing. Tested by our top cold-water pros in slush-waves and water temps down in the low 30s, the 1mm Neoprene Heat Boosters utilize the same plush, quick-dry lining as our Custom Pro and Custom LTD boots. Seams are purposely offset away from the split toe for maximum comfort and low-profile inside the boots. But wait, there's more! The low-friction surface means your boots can be taken off/put on very easily. Since the Heat Boosters are independent of your boots, they can be rinsed/dried very quickly to insure warm, dry feet for multi-session days. 1mm Neoprene Heat Booster Socks can be used inside any brand boots, round toe or split toe. Keep in mind the 1mm thickness takes up a little more space inside your boots , so if you are buying new boots, make sure there is a little room inside the boots to accommodate the 1mm socks. The 1mm Neoprene Heat Booster Socks are available in 4 sizes: Small: US Men 6-7.5/US Women 7-9 Medium: US Men 8-9.5/US Women 9.5-11 Large: US Men 10-11.5/US Women 11.5-13 XL: US Men 12-13+/US Women 13.5+
