- Made from tough high quality 5.0mm "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.
