These socks are absolutely amazing. They grip really well and the grips slowly erode away in order to give the perfect amount of grip you need on marley or wood floors. Best part? You can make the grips sticky again if they get too slippery with a spray glue called E6000! Literally spray it on, let it sit for about 5 minutes or less, and the grips will be as sticky as when you first bought them. its outstanding. Even wearing them in the shoes I use for hip hop, i feel a difference with my shoes not slipping off of my feet. its amazing! I plan to buy, at least 4 more pairs, for now.
