"I never wear heels but can wear these all day. I bought them to wear with a suit for an interview, and they are now my go-to heels for work.
Not only is the heel small enough that my feet didn't ache, but the shoe is made of soft flexible fabric that doesn't rub or blister the way hard leather shoes do.
The only downsides are that the "black" pair look like grey with a black cap on them, and they took me about a day to wear in. They didn't hurt me the first day the way heels normally do, they just weren't as completely comfortable as they are now."
