Super comfy and stylish, I’ve never worn these styles of loafers however I’m glad I purchased these. I’ve purchased another pair in a different color.

Meh
Size: 10, Color: Black
I had a real leather version of these shoes for many years. They are still totally wearable, however the soles have worn smooth from using them so much. so naturally I buy a new pair. These are the same design. the stitching is close, the pattern in the leather is the same. But they are so much cheaper. There is no real leather. It's all synthetic. The sole is not the same quality of rubber. The stitching is not as good. They look fine, brand new, yet I am sure they will not last. these are cheap. They also cost less, so I guess they are an average value, but I am very annoyed.

Very satisfied with the fit, style, and quality of these shoes. Usually scared to buy shoes online due to the sizing issues or difficulty. These were no sweat. Good delivery as well.

Doesn't really slip on too well.

Doesn't really slip on too well. Also, since the heel is ridged it unintentionally allows my heel to slip out while walking.
