Great socks. I feel fit better than Sock Guy or Defeet. More form fitting yet easier to take off. This particular model runs thin so if you are looking for a cushiony/insulated sock, this is not the one.
The threads on the inside are abundant and can catch a toe nail when putting them on. The threads also cone through on the outside of the sock which I took scissors and trimmed.
The high cuff on this sock supports my calvesachilles nicely, and stays in place during long rides without feeling overly constrictive. Medium weight material breathes well in warm weather and doesn't crowd space in your shoes. For reference, I ordered a size Medium sock and wear size 42.543 shoes.
