The stainless steel fin strap has several advantages. No need to adjust it, as it automatically adjusts to your fin and foot.
To choose the length of the stainless steel spring for your fin, slip your fin over 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 (example here 360mm for size XL), 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.
