Fourth Element Thermocline Fin Sock

Experience comfort and protection with these Finsocks, designed to be worn under full-foot fins or neoprene boots. Made with soft, fleece-lined fabric and flat-lock stitching, they reduce friction, prevent blisters, and minimize irritation from rubbing. Finsocks also provide extra warmth and make it easier to slide into wetsuits, while helping slightly oversized fins fit better—perfect for children, teens, and adults alike.
