3mm neoprene. Perfect for freedivers - protects your feet from chafing damage and water climate when wearing full-foot fins.
Features include:
- Made from tough high quality 3.0mm "CR" neoprene. NOTE: be wary of buying socks made by "SVR" (polyester) neoprene which is cheaper but is not as durable, or as warm as "CR". "SVR" is also highly flammable!
- Additional sock panel for extra shaping and fit
- Seams are glued and stitched for extra durability
- Non-slip ripple sole
