With this stainless steel fin strap, you no longer need to adjust the strap on your fins!
To ensure that the stainless steel spring is the right length for your fin, slip your fin on with your shoe and measure the distance between the two hooks.
Take the size directly above the stainless steel spring, S (300mm), M (320mm), L (340mm), XL (360mm) available on our site.
The length indicated (here 320mm for size L), is the length between the two hooks at the ends of the springs, in the middle of the hook circle, which corresponds to the length between the two hooks on the fin, passing through the heel.
