Classy pair that look great but don’t last
Size: 12, Color: Black, Size: 12, Color: Black
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

Great shoe, horrible lace design.
Size: 13, Color: White, Size: 13, Color: White
This shoes look great and the materials for the actual shoe feel great. They run a little big that doesn't bother me. Unfortunately, the lace design is horrible. I've now have 2 pairs of these shoes and both times the bottom lace has ripped out of the stitching. The first time was on the 2nd day I wore them, and the replacement pair to those it happened after I walked 20 feet. Both times I've tied a knot in the bottom lace so that I could get through the day. Ideally these laces should be connected together and not attached to the shoe (this is how both of my Skechers Slip-ins are designed). Because I like the rest of the shoe so much I'm buying elastic laces to replace the horrible original laces.
