Great fit
Size: 13, Color: Ironstone Canvas/Ivory
I picked these up at a reduced price. Speedy delivery. I work in retail and I'm on my feet all day. I have wide feet so I purchased a size larger. They are very comfortable. These were a perfect addition to my wardrobe.

These shoes are very comfortable and light. Also good price for a nice decent shoe line that’s not made cheaply. I like the quality and the comfort of these shoes.

Not very good quality. They are comfortable but they make this weird clicking sound when I walk. Wouldn’t buy them again.
