These are not the same quality socks that I have purchased in the past year or so. The materials content/proportion has changed. The fabric is thinner in my opinion and does not hold up to quality that I have come to expect. Also, for some reason, the color of the white/blue/grey socks has different, inferior blend of material content - which unfortunately is reflected more in the heather/grey socks. I returned these socks and am now in time-consuming pursuit of a brand that produces consistently reliable and quality cotton crew socks.
