I was pleasantly surprised by these socks. Usually, thin no-show socks are simply a "no-go" for me, as they slip down immediately and I have to throw them away. But these stay in place all day, and are comfortable all day. They are very cool and lightweight, and the silicone at the heels keeps them from slipping down. And they really are no-show -- I wear them with my Sketchers slip-on shoes.I'll definitely be buying more of these.
