Designed to wear inside all round-toe boots or swim fins, the Round-Toe 1mm Neoprene Heat Booster Socks boost warmth by 5 celsius (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 just above freezing, the 1mm Neoprene Heat Boosters utilize the same plush, quick-dry lining as our Custom Series boots.
For extra durability against the front of boots or fins, the toe-seams feature external Tatex LSS (Liquid Seam Seal).
Our 1mm Neoprene Socks are also quickly becoming a favourite as a swim-fin liner for bodyboarders, bodysurfers, and photographers, providing a comfortable buffer between feet and fins, and adding a bit extra warmth and protection.
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 Round Toe Neoprene Heat Booster Socks can be used inside any brand of round-toe boots. 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.
