Stylish comfy shoes

My husband adores these shoes. They are true to size. Comfy and stylish and lightweight which makes the ideal combo for him. Glad I purchased them.

Good shoe!

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.
