This sock is SUPER thin.  Let's go over the seller's claims:
-Enhanced elastic grip construction in both arch and ankle to provide ultimate support and second skin fit
  *There is virtually no support as the material is way too thin to even make that claim.
-Unique Triple-Y heel creates a deeper heel pocket, ergonomically formed to the shape of your heel, for ultimate fit and comfort
  *again, the material is way to thin for a "deeper heel".  It's like running in business socks.
-Low volume construction
  *if by low volume they mean using as little material as possible, then they got this one right

I wouldn't buy again.
