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.

No Bending Required, No Hands Needed
Size: 12 Wide, Color: Cognac Napa Leather
The shoe is a good fit and run true to size, and color and quality are as advertised. Easy to slip on and off, without bending to do it.
