Wonderfully comfortable, but eventually wear out

I wear PhD crew socks (light, medium, and heavy) all year 'round. I bought these to replace a pair of medium-weight PhDs that was wearing out in the mid-foot. But the heals, seams and elastic have been bullet proof. Couldn't bring myself to give 5 stars, though.
