The almighty Band-Aid Blister Block Stick.
This little deodorant-like stick will save your feet, I swear. You know those fabulous 4 inch stilettos sitting in your closet, that you've worn once but promised your poor feet that it would be the last time? Never again. Through many years of research, I have found that it takes a minimum of two full days of wear for a shoe to no longer give you blisters, but once broken in, those once-painful shoes could become one of your most comfortable pairs. This magic stick will get you through those first two wears, no problem. Just apply the stick liberally along your heels and anywhere else you expect the shoe to rub, and voila! You'll be blister free all day long. Just be sure to apply BEFORE the blisters begin to form. Otherwise, might I recommend these:
