Great concept, but not great for all sneakers. I used them on Converses and the little anchors on the inside of each eyelet really dug into my feet. I'm 5'2"/110lbs - pretty thin and boney, so there is no reason for my foot to feel strangled. I wear them w very thin no show socks. I swapped them for the longer ones in the package but still dug into my feet. Will try with a running sneaker, but not w converses ever again
