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 (and more space than our regular knit Heat Booster Socks), so if you are buying new boots, make sure there is a little room inside the boots to accommodate the 1mm socks.
