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.
