The pros are that these socks have a good feel and don’t creep down your calves around your ankles over the course of a day. The cons; however, are that I’ve had to repair the top hem of one (1) of the eight (8) socks after the first wash-dry cycle AND the material surface changes texture to a frayed surface after the first wash-dry cycle. Now I air dry the socks on a line after washing them on delicate cycle to prevent further damage.
