I have lots of red sores on the bottom of my foot they are painful they feel warm and slightly itchy when itouch them they are sore hurts to walk?

To start with...: It may be athlete's foot. The best otc medication (in my opinion) is lotrimin (clotrimazole) ultra. Socks should be a synthetic material like those manufactured by thorlo [http://www.Thorlo.Com/]. Dilute vinegar soaks are good as well. Dry the inside of your shoes by placing them up-side down over an air return vent at home overnight. If this doesn't make things better in a couple days, see a podiatrist.
