Decent product. Holds foot into heel of shoe tightly which is great. A little hard to adjust so band at top doesn't cut into front of ankle, because it slides through eyelets a little easier than standard laces.

Most annoying aspect is loose end of lace wants to slap top of shoe as I walk. I end up tucking it under one of the cross laces, but it would be nice if it had a way to clip to them instead.

Haven't worn it long enough yet to determine durability.
