Comfort and Appearance
Size: 9, Color: Black
The shoes were as advertised. Marc Joseph (I hav 4 other pairs) are the perfect shoes for me with my physical needs. Additionally they are exceptionally comfortable and attractive. This pair I returned because they weren’t quite the right fit for me. They are, like my other Marc Joseph shoes, very well made and very attractive.

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.
