Good Quality
Size: 11, Color: White
Nice looking shoe. Slides on easy. My only feedback would be I wish the toe box was a bit wider and the heel a bit higher. It's a good shoe overall. I would buy again.

Great shoe. Slip on is easy and the shoes are comfortable and classy.
Ten months later and the bottom has holes and didn’t last.
