We love the Drone Low Volume Climbing Shoe because it offers the aggressive, downturned profile we like for bouldering and sport climbing with attention to detail on the fit. The rubber sole and toe area are stretchy and thin to provide a hyper-responsive feel for micro-footholds that tend to appear on difficult problems. This low-volume offering is ideal for narrow feet and shorter insteps, but Mad Rock also makes a high-volume version of the Drone Shoe for larger foot shapes.
