1 Pair 3mm(L) Wetsuit Socks, Non-Slip Neoprene Scuba Boot Socks for Men, Women, Snorkeling and Surfing 1) Our socks can be worn alone or in combination with diving fins. 2) Diving socks: Made of high quality material, 3 mm neoprene + nylon, guaranteeing great elasticity, long life and exceptional thermal insulation; their textured design slows the temperature drop of the feet and protects the feet from certain sharp objects during use. 3) Note: the bonded seam technology used on the combination socks makes the seams invisible. This slows water penetration and increases the life of the sock. However, wetsuit socks are not a fully waterproof product, but a diving accessory that can be used in conjunction with a wetsuit to protect the feet. Over time, water will inevitably seep through the seams. 4) Non-slip design on the flat of the foot helps increase friction. Ideal for scuba diving, surfing, snorkeling, swimming, sailing and other water sports. The rubber bumps on the bottom of the socks make them uncomfortable for climbing over rocks or walking on flat roads.
