Cressi's Palma short 3 mm socks are manufactured from a superelastic and ultra durable nylon 3mm neoprene rubber. These socks are great for either full foot or open heel fins. The socks are lightweight and a great addition to the traveling diver's gear bag. Socks are extremely comfortable with a grip sole design to assist with non-slip on wet surfaces such as boat decks and slippery ladders. The Palma is built to last with glued and sewn seams for strength and durability.
