The NEW FX Pro II Heel Straps are the sickest heel straps in the sport - light, comfortable, secure, and ohhhh so stylie. Improvements upon the original FX Pro heel straps include double cam-lock adjustment on each strap to help you dial in the perfect fit, softer EVA padding with lycra protective layer, durable synthetic leather outer layer and edging, and ladder strap tunnels to keep your straps looking nice and tidy. If you want to ride without heel straps for certain tricks or terrain, just flip the FX Pro II Heel Straps up over your bindings where they'll stay until they're needed again (next trick, next ride, or even next season). FX Pro II Heel Straps come stock with Cam-lock Buckles. For riders with F2 bindings or F3 Cam-lock bindings, or for any "adjust-aholics" out there, MBS recommends upgrading to F3 Ratchet buckles. FX Pro II Heel Straps are not compatible with F1 or Freeflex bindings.
