Football can place a great deal of stress on the foot and the more you play, the higher the stress. There can be a lot of friction involved, particularly when playing on surfaces such as Astroturf. A player often stops suddenly and twists and turns. Likewise, when playing on hard ground the studs can result in pressure to the sole of the foot. Football boots can be quite stressful on the feet, particularly as most players wear a tight fit for better ball control. It is not uncommon for a footballer to suffer with pressure points, corns, callus or ingrowing toenails as a result of football boots. This is particularly damaging to those who are still growing.
