Several skin conditions can impact on your feet and plenty of wide spread skin problems that affect the entire body will be even worse in the feet because of the use of shoes and especially the strains that athletes put on their foot.
Blisters are frequent on the feet of runners. They are because of light friction from your running footwear on distinct areas which ends up in the skin layers getting split up. This can often be on the toes or even the rear of the heel. Nearly all runners are incredibly acquainted with blisters. The easiest way to manage blisters is usually to not get them to start with. Ensure the running shoes fit appropriately and use a lubricant on areas of high chaffing. There are lots of friction reducing tapes or strapping which athletes can use to prevent blisters if they happen frequently. When a blister will happen, then make sure it's guarded and cushioned to allow it to heal up.
Corns and Callus
Corns and calluses develop from to much force on an area. This generally is due to the shoes not fitted adequately or there's some deformity causing higher pressure for example a claw toe or bunion. Corns and calluses are not too difficult to take out. A skillful podiatric doctor could easily take them out with debridement. What's less than easy is to prevent corns and calluses returning. Foot corns do not have roots which they grow back from which the podiatric physician just didn't take out. It is just a common misconception that corns have roots. Corns and calluses consistently return in case the trigger isn't taken away and that cause is the increased pressure on the corn or callus. This pressure will be reduced by, for example, surgery to fix a hammer toe or hallux valgus. Foot orthotics should help minimize stress on the bottom of the foot should there be calluses there.
