Hammer toes are toes that bend at the middle joint and can cause the toe to rub against the shoe.
To decrease the blistering I would recommend a gel toe shield or toe cap to reduce pressure and friction off the toes. You also want to consider the size and type of shoe you are currently wearing. A shoe with a high toe box will provide enough room to accommodate your hammer toes and decrease friction between your toes and the shoe.
