Very nice and minimal[This review was collected as part of a promotion.] Bought two pair of these for walking. They fit properly, based on size chart, don't slip, and are quite cool and comfortable in the heat. My first venture into wool socks, and I am very happy. Love that they do not retain an odor, launder well.

Very comfortable![This review was collected as part of a promotion.] Really comfortable socks - I wanted the fabric to be just slightly thicker, and maybe for that reason they fit slightly small, but they're comfortable and they get the job done!
