Powersox appear to be made by Goldtoe- a good quality brand I buy often for my teen. These socks are fairly lightweight, comfortable and don't add bulk or change the fit of my sneakers.  With weather already in the high 80s, I appreciate the low cut that hits just above the ankle, as well as the mesh material that has a bigger weave that allows for some ventilation. A ribbed band in the center wraps around my foot to add a bit of support to my arch, though the support isn't comparable to a compression sock. Although lightweight, these do provide a bit of a cushiony feel underneath. The elastic ankle band stays in place and isn't too tight. Ive worn these with my Skechers slip ons and had no issue with the heels slipping down.

The material is a synthetic blend that feels soft and stretchy. Because of the stretch material, its recommended to dry these on a low setting. Ive only washed them once and did dry them on low, and they came out looking like new. These are sporty, good looking socks in a nice mix of blue, black and gray colors. The sizing seems right as I wear a size 10.5 in womens shoes (42 Euro) and these socks are a good fit (plenty of wiggle room in the toes but not saggy) even though Im at the smaller end of the range of the Mens size Large. My son wears a size 12 shoe and these fit him too, but any bigger and Id size up. These ankle socks have a unisex look good for men and women. My son prefers his white Goldtoe quarter socks as hes a creature of habit, but I find these comfortable, like the fit and also like the colors for me. 4 stars.

PS: To clarify, I refer to these as ankle socks as they're not what I think of as no show socks. These cover my sons ankles and show with his Vans and likewise cover my ankles and show with my Skechers.
