Had a very difficult time with these.  Ordered 2 pairs thinking I'd love them like everyone else.  Went to put them in my new Asics and the holes weren't big enough so I had to use pliers and kept cutting the lace to fit.  Then the cord started cutting the top of my ankle where it rubbed.  Didn't have this problem with flat laces.  Wish I could return the second pair now. Will probably take them out of my shoes b/c the rubbing hurts.
