Hi
I can suggest u one foot care method to get rid of sores. Take warm water in tub mix one spoon shampoo one spoon facial bleach powder and one spoon hydogen peroxide. Soak ur feet in water for 10-15min then use ur footfile gently to remove dead cells. Wash ur leg with plain water let it dry properly. Now u can apply any nourishing cream and put on ur socks. Take care dont let ur feet catch dirt atleast after doing this till 4-5hrs. u can do it weekly . but daily u have to wash ur feet properly and apply cream and rest.
bye
