The other option of snorkeling fin-wear is closed heel fins. These fins differ than open heel in that the fin silicone extends to completely surround your foot and heel, which makes the foot pocket much smaller than the open heel fins. Because of this, socks are not able to be worn with the fins which leave them a popular option typically reserved for warmer waters. Since full foot fins do not have adjustable straps, it is very important to get the proper size for your foot. The fin should not be able to wiggle around on your foot but also should not be too tight to where it may cause cramping. The advantage to these fins is that your foot is entirely surrounded by the fin instead of a fin strap and gives it a more snug, secure, & tighter feeling. However, whether you choose to purchase open or closed heel fins, the most important thing to remember is comfort and fit for an enjoyable snorkeling experience!
