They are back!
Color: Quartz Stone, Size: 38W x 32L
The quartz stone (my favorite color) has been sold out for at least two years. It was looking like this style was going away forever. I check my wish list last week and they are back! Same great quality as before.

Good buy, great fit!
Size: 12, Color: White
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.
