My son's feet were so bad, I took and added alittle bleach, (this will burn raw feet so add just a little the first time) then slowly add more till he can stand it this will stop the iching. and put him in white cotton socks. Soak everyday and it will kill all his problems. You will also have to bleach the tub and shower and if he uses public showers get him a pair of flip- flops or he will keep getting it when you stop the bleach baths. my sons quit.
