Bought these for my son. When he first put them on, a piece of "lace" came loose from where it was attached. I took a needle and thread and just reattached it because it was an easy five minute fix. The third or fourth time he wore the shoes (not worn, only around town) his big toenails started to wear through the material of the shoe. He has normal, trimmed nails. I'll try to figure out how to get them back when I have a few extra minutes.
