Before you reach for the duct tape and vet wrap, just buy those ridiculously expensive blister plasters. They are for avoidance rather than treatment so put them on any area where you might expect to get a blister, or as soon as you feel that suspicious warmth. Don’t try to take them off. The plaster becomes a second skin so you just have to let it fall off naturally.
