I wish I could afford 100 pairs of these! They stay snug on my feet and don't pull down into my shoes while walking. They sit low enough that they're not obvious I've got socks on at all. They wick perspiration so my feet feel dry and comfortable. Medium thickness - thinner on top and padded on the bottom, but they're neither too thin nor too thick. There's a seam across the toes, but it's done so well that I can't feel it (I wear other socks inside out because the seams bug me). I thought they were a little pricey, but they're excellent quality, so that's worth it. You know how some socks are almost slippery and your feet slide around in your shoes? Well, these don't have that problem. They grip my feet and my shoes, so everything feels just right.
