These socks are great fitting, durable, and sharp looking. I had originally ordered a pair to make the $50 mark for free shipping but have been so impressed since receiving that I have ordered more.
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.
