Sometimes overlooked as an essential piece of dive equipment, having a properly fitting pair of fins will greatly add to the enjoyment of your dive.
A pair of fins that is too loose may cause painful blisters, and you have to constantly worry you’re going to kick them off. On the other hand, you don’t want them so tight they’re on your mind the entire dive.
The fit should feel comfortable, like natural appendages, like they’re not even there.
In this short guide, we are going to show you how to properly size both full foot and open heel fins, as well as a fin size chart to help you make the right choice.
Sizing Full Foot Fins
When fitting full foot fins they should be snug, but not too tight nor too loose, and should be sized according to your shoe size.
Many manufacturers may size fins across a few sizes (For example, 8-9, 10-12), in this case, your toes might stick out from the front of the foot pocket, this is perfectly fine unless it feels uncomfortable. If it does, then you should get the next size down.
Sizing Open Heel Fins
Open- heel fins are not generally size by shoe size, but by bands (for instance, M, L, XL). Use the size chart below to choose the right shoe size for you.
A general rule of thumb when buying your adjustable open heel fins is to add one size up to leave room for your booties. When trying them on for fit be sure to do so with your booties on. (Learn how to choose the best dive boots)
