Its airy, moisture-wicking fibers consistently draw moisture away from your skin to keep your entire foot dry from your warm-up spin to the last climb of the day.

Perfect sock

  • Familiarity: I've used it several times
  • Fit: True to size
  • Size Bought: XXL

I'm a big fan of these socks. Thin but supportive. 13cm is the perfect height. I'm a size 12 and XXL fits well.

Classic road socks

    This appears to be the new '17 version. New colors and streamlined detail at the top of the cuff. Same great socks.

    Top features:
    1. These socks are very thin. Snug around the shin (so they stay up). Highly ventilated along the top of the foot. Nice midfoot support band.

    2. Highest quality, top-of-the-line textile, (meryl skinlife) is silver infused so it inhibits bacteria (and thus sock stink). The socks are made in Italy.

    3. 13 cm is the most common height seen in the pro peloton.

    In very hot weather (>90°), I use Castelli's even more ventilated Free 9s.

    Sizing: In my experience, the official Castelli size chart is best. Euro shoe size >45 =XXL.
