Knockoffs are a tricky subject and seem to keep coming up lately. I'd never buy or wear a fake, but something "inspired by"... well apparently I have and would again. Probably one of my most worn pair of heels were "inspired by" a pair of Miu Miu double-strapped maryjanes. The Miu Miu pair had a 4.5 inch heel, and were quite gorgeous, but harder to find and out of my price range at the time. When Steve Madden's line "Steven" came out with this similar pair, I quickly ordered, paying nearly full-price. I didn't wear them for at least six-months because I found them uncomfortable, yet when I brought them out again last year to wear with something I found they actually were quite comfy after being broken in. They are my staple black shoe that can be dressed up or down.
Sizing is true, to slightly small in my opinion. These are the 7.5. I tried the 7 but it felt too snug with tights for the winter. They gap slightly in the back, but the straps keep them securely on my foot. I can walk miles in these shoes, unless some of my other 4" numbers.
