I Love Them

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: XXL

Very thin. Very comfortable. Will buy more.

It's a sock and works

  • Familiarity: I've used it once or twice and have initial impressions
  • Fit: True to size

Recently, I gave a one star for the Free Kit 13 Castelli sock. It sucked. These are much better. Still could use more stretch, but they're more than adequate. my favorite from them still is the Corsa Rosa. Consistency would be nice.
