The "EDGE" is essentially a flat area that you grab onto. Usually, a challenging hold for the beginner as you cannot dig in or get behind the hold for a more positive grasp. Easier to hold than the "CRIMP."
With large-type labeling, the "FOOT" hold informs the climber of the hold type and educates them in a natural, hands-on manner. It's ideal for climbing classes, DIY walls, and other applications.
