Just in case your binding spontaneously combust.  The Burton Cord Leash is a great way to stop those run away boards from happening.  Many of the places we ride actually require you to have a leash too for safety reasons.  So buy one, and then you won't have to worry about going back to the car and pulling a shoe lace to get past the lifties. 

Features:

• Heavy Duty Metal Connector
