Designed to wear inside any style boot, the new Solite Thermal-Rebound Heat Booster 1mm Split Toe Socks boost warmth by 5-10 degrees Fahrenheit. This can offer longer sessions in frigid water, where you can focus on performing, rather than freezing.

Tested by the top Solite cold-water pros in slush-waves and water temps down in the low 30s, the 1mm Neoprene Heat Boosters now feature the Solite Thermal Rebound interior lining fabric for a 10% increase in warmth. Seams are purposely offset away from the split toe for maximum comfort and low-profile inside the boots.
