Edging Rock Climbing Shoes Edging shoes often have supportive 'board lasting' inside the shoe to take the 'edge' out of standing on one. In general, these are stiff and are recommended for the beginning climber as they have a lining that protects the feet and are easier on the leg muscles, especially the calves.
