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

These fin socks are primarily designed to keep your feet warm and prevent your fins from sliding off. I'm not entirely sure that one needs them in warmer tropical waters, they would probably work better in water 72 degrees or below since they are quite thick. Fins are generally designed not to slide off anyway, so again in warmer waters they don't provide a lot of benefit. This is a nice product though, these socks provide a non-slip traction after use they dry quickly, like swimsuit material.
