Blast your heels with heat. Heat is an effective way to soften a material and make it more pliable. Carefully warm your heels using a blow dryer or a small heater for about a minute or two. Watch how your heels react to the heat because certain materials don't do so well under heat for long periods of time. You can bend and twist your heels while they’re still warm. Or you can wait until they’ve cooled and put them on with a pair of socks to stretch them.
I read about this stuff in some magazine at the salon (O, inStyle, Vogue? not sure which) and since high heels are not my best friend, I decided to give it a try. First time I used it, I was totally dressed except for my shoes when I remembered it, so I sprayed it on through my hose. The menthol scent was a kind of strong at first but it went away after a couple minutes. It felt cool and kind of tingly. I waited a minute or so until it dried some then I put on my spike heels and went off to party. Pretty amazing-- nearly 4 hours later I wasn't in any pain even though I 'd been standing nearly the whole time. I used it again the next day for work and was able to stay in my heels all day--a record for me. I did have to touch it up after about 5 hours but then I was good for the rest of the day. It wasn't greasy and didn't stain my stockings or shoes. Good stuff!
I’ve heard people argue that my new, near-daily ritual is ridiculous, that no shoe is worth that much pain or effort. But how different are heels from other small rituals we undertake every day, such as applying makeup? The payoff in terms of the confidence I feel when stomping down the street in a pair of killer heels is worth way more than the extra 30 seconds added to my morning routine.
