Put inserts under the insole in the area that the blisters are. Inserts only help depending on where you blisters are. You can get them at shoes and sports stores. I also recommend band aids they have special ones just for blisters they are really good.
go to ur local cvs or walgreens or rite aid or something nd look in the band aid, brace isle nd find mole skin. its not actuall mole skin, it a peachy tan color nd its fuzzy/soft on one side nd stiky on the other. my suggestion is to. cut a peice and than stick it to the shoe area tht hurts u. trust me this works...im a minor league soccer player nd i use this like air!! hope i helped!!
