It's a well built product, but I read in the questions section that this foot fitter works for high heels. That's definitely not true. It's too straight to fit into heels as the sole of the shoe is curved. And don't bother with strappy heels. I wanted it only for the strap around the sole of my shoes to widen. It didn't work. It's more limiting than I thought.<br /><br />So basically I can't use it for the reason I bought it.
