Here’s the size chart to help you choose the right swim fins. Simply select your size using your usual shoe size (EU).
It’s important that your swim fins fit securely without pinching. If they’re too loose, you could get blisters and lose power with each kick, making swimming harder. If they’re too tight, you might end up with foot cramps.
The chart also lists the total length of the fins (measurement A), which is especially handy to know if you’ll be packing them in a suitcase for your trip.
