Good buy, great fit!

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.
Size: 11, Color: White, Size: 11, Color: White
Doesn't really slip on too well. Also, since the heel is ridged it unintentionally allows my heel to slip out while walking.
