I am so thrilled with this stuff! I'm size 4 and a half, my feet are wider than normal('E' fit), and I have plantar-fascitis. Due to this it has been EXTREMELY difficult finding shoes to fit my feet. Any shoes or trainers I tried always seemed to be tight on certain points and dig in to my feet after walking in them - even if they hadn't seemed too bad when first tried on. I had began to think I was doomed to have to try on hundreds of pairs of shoes just to find one pair that didn't crush my feet. This spray has changed all that!
When I first heard of this product I was sceptical, but willing to try anything. Wasn't convinced that a spray-on foam could 'stretch' my shoes but hadn't had much luck with traditional wooden shoe stretchers and was running out of options. Amazingly, it actually works. You simply shake the can, spray the areas on the shoe that you want to stretch, then wear the shoe for a few minutes. The spray softens the leather, so the shoe then moulds to your foot as you're wearing it.
You can treat the inside and the outside of the shoe unless your shoes are patent, reptile, or brushed leather, in which case you should only spray the inside. I find that in most cases I only need to treat the inside of the shoe anyway, and the shoe still has plenty of 'give'. With most of my formerly unwearable shoes I've found one application to be enough, although some really tight shoes have needed a couple of 'stretchings'.
I now find that I have a lot more options when buying shoes and can even buy without trying on, because if I find they're too tight I can stretch them to fit my feet. Fantastic!
Now if only someone could invent a 'bra stretch spray' so I could actually get a bra that fits, I'd be all set!
