I got six pairs of this sock from TJs and they are my favorite tennis socks now. The elastic opening provides just the right traction to stay on.  The three Adidas classic stipes at the bottom of the foot add cushion and some compression.  Overall, the construct of the sock make you feel that sock is pressed comfortably onto your foot in all areas especially from the bottom. When first putting on your shoes, there might be a little big of the edge showing than expected (depending on the shoes you wear - I wear the Nike Air Max Breathe Free II); but as you move in sports, the sock will adjust nice to become no-show but definitely will NOT slip down like some self-proclaimed non-slip tennis socks. I really love them and will keep wearing them for all my games.
