Cross-training — allow some toe room for plyometrics. Many sports require participants to do some cross training to improve their reflexes, strength, endurance and jumping ability. Toe room is a must when athletes need to do plyometrics to improve their vertical leap.
Running — no heel slip. Runners need explosive power without putting too much stress on their joints. For that, they need a little extra toe room and room for the heel to move without slippage, which can cause the foot to twist, putting extra strain on the athlete’s joints.
