Runs tight. Skinny and smaller than other brands.
Size: 8.5, Color: Brown
Comfy and lots of support. Cushiony. Beware: the brown I ordered runs small. Tighter than other brands.

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.
