I've been getting really bad blisters from boots every since I started playing in them. My current boots are Nike Total 90 III (15 plastic studs), they comfortable but I still get blisters from them. They're only a little big for me, about 1cm from the tip to my big toe. I've tied them tighter, looser, and normally but the blisters still appear. I only get them on the meaty part below my big toe, right on the border of the side and bottom of my foot. Any suggestions to stop the blisters?
