You may remember a thread I started awhile back asking about how to deal with blisters, etc when not wearing nylons with heels.
I've bought a ton of different products and here are the best two I've used:
For pre-empting blisters this stuff is amazing. when you can feel where your shoes are going to rub, put this on immediately before there's even a hint of a blister and you won't get one. There's also a Band-Aid brand product called Friction Block which I'm sure is just as good.
When you get a blister, these are the most amazing band-aids ever. They form a cushion (the band aid expands) over the entire and exact position of your blister almost like it blows up like a balloon just over your blister. It takes a few hours but it's amazing. They stay on for a few days even through the shower so you don't have to take them off and lose that amazing cushion. There is absolutely no pain even with a fresh blister and the same shoes with these band aids.
Thanks to everyone that helped me on that thread - I wanted to report back on the best results!!!
