The 701 Surf Strap, as with nearly all my surf mods, are product of R&D with the best freeriders not only in Aus but from other countries as well. Your foot needs to be secured in a foot hold, not just hanging under some bracket . If your foot was to come free while doing a trick it could end bad. The tapered design of the Surf Strap makes it fit any shoe. The smaller the foot the more it goes in. Being a urethane, not only impervious to the elements, but stretches and forms around your foot. These Surf Straps will hold you in, but simple lift your heel, and you can easily remove your foot. A lot of riders fit straps in the wrong place. The 701 Surf strap is designed to be fitted at the base of the angled section. This allows you the freedom to move your feet without the restriction of the strap. When it comes time to lock in, you simple kick into them. The straps that are fitted where you stand, end up being a pain as you are always standing on them. The Surf strap being moulded, if you do stand on them , they will flatten ,but will go back to there shape as soon as you step off them. I have seen many other brand straps just stay down after standing on them for a while. Every thing about the 701 strap has been well thought about and tested by the best to give the Blaster riders the very best money can buy. Its not rocket science, your feet need to be SECURED for freeride tricks.
