What do you do when you get that feeling that a blister is in the making ? I have tried a piece of duct tape applied directly to the skin. It seemed to work last year. Any other suggestions for prevention other than well worn in boots of course? I lace up as tight as I can take it anyway and wear smartwool socks. How about after you have a blister and still have several days of a backpack hunt to go and a multiple mile pack out ahead? I haven't had it happen yet but dread the day I do.
