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.

Love it
Size: 11, Color: Black
Almost the perfect travel shoe. Goes well with both casual and formal attire. Walked like a million steps with this in Japan, SEA, etc. only thing it probably can't do is probably hiking. Otherwise the leather feels really high quality, and the shoe slips on without much fuss. I'd describe the style as: a dressed-up Converse
