Ok in a pinch. Can get better shoes for the price. Wide aren’t wide
Size: 9 Wide, Color: Black/Black
These were ok comfortable. Would have preferred at the price point to be a little more comfortable. For being a wide size, the shoe was rather tight on my feet. Quality is ok. It passed for the wedding. Would probably have taken more time to pick something different if I had the ability to. This was a last minute purchase.
