These thermal Freedom 4mm neoprene wetsuit swimming socks, from C-Skins' Swim Research, range look set to surpass the already popular C-Skins Legend socks with more advanced technical features to set them apart.

New construction technology produces an optimum fitting design, as the form/shape of the sock hugs the contours of the foot offering a superb, well fitting swimming sock all helping to encourage thermal protection. The top of the sock features a lockdown (ankle) cuff, an inner glide skin finish creating an improved seal around the lower leg to help virtually eliminate potential water ingress. This optimal fitting sock combines 4mm thick double lined neoprene with C-Skins' Thermotech poly pro lining to offer improved thermal protection while the super hydrophobic neoprene exterior and glued and blindstitched seams produces a pair of flexible, comfortable and well fitting open water swimming socks.
