If you're like me and you're feet tear apart every spring when you switch from boots to shoes, this won't be the holy grail, but it'll help. I find this doesn't really make a difference on my heels, but does work on the straps of sandals or anywhere a strap might rub. I've tried both the name brand and the store brand and they work exactly the same. Worth having in your purse.

I use this when I wear heels or flats, which tend to cause blisters and are just uncomfortable. I find that it does help somewhat, but it does wear out after awhile so you need to reapply and I still got some blisters, but they weren't as bad as they would be if I didn't use this. I don't think this helps the problem 100%, but I would recommend it as it is a helpful product.
