The Anti-Slip Neoprene socks come in various patterns and are made of thin, single-lined, high stretch neoprene. The inside is lined with Metallite, making them easy to put on and take off. The sole has a non-slip lining. These socks can be used with closed foot fins for protection against scratches and chafing, or with firm-soled boots and open-heel fins for warmth. Designed in Italy by Cressi and manufactured in Cambodia, these socks are from a renowned Italian brand that has been involved in scuba diving, snorkeling, and swimming equipment since 1946. They feature a speckled Reinforcing and Anti-Slip Coating, making them non-slip on wet surfaces like boat decks and slipper ladders.
