Review on Tilos 3Mm Waterproof Neoprene Fin Socks - Ideal For Scuba Diving, Snorkeling, Swimming, Watersports, Hiking & More! by Bobby Cantu

My husband thinks these might have helped for his new fins not to stay on-both fins slid off of the back of his ankle within minutes and his fins were extremely tight before he went in the water. But it's hard to say since we never got to try the fins without these socks (one fin got away). But the socks are a good quality and we'll use them anyway as water shoes for when we go kayaking because he hates his cheap water shoes from Walmart.
