I really wanted to like these shoes. They are well designed and built, look great (had green ones), lace system is terrific, etc...  They also felt great (no need for insoles) except for one issue; the heel keeps lifting out of the shoe a bit. Not a lot, but enough to annoy. No matter how hard I tightened them they move up. I even tried one size lower than I usually take. I noticed someone else mentioned this as well. They have big padding at the heel so maybe that is why. Either way, I'm disappointed they didn't work out for me.
