With our new improved technology, our fins will fit securely in your fin box, no matter how wide it is. This means no fin wiggle.
These buttons are what will keep your fin secure in your fin box. Each fin comes standard with 2 green and 1 blue button. This combination works with most brands we have tried. If you need a different combination, you can order extra buttons here.
Thanks to founder and inventor of the Kumano AI Buttons Michiaki Ishida.
