Bacteria-free for the road.

In addition to the secure, gently compressive fit of a midfoot support band, Castelli's Phanta Bike Socks incorporate Meryl Skinlife fibers in order to fight odor-causing bacteria. While the two aren't necessarily related, they are the most important ingredients in any cycling sock. For those who aren't into the latest mid-calf dinner sock trend in the peloton, the Phantas are low enough to be all but invisible, just showing above the edge of your shoe with a higher back that prevents the sock from slipping down.

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

As far as socks go, these are pretty swell. They fit true to size- I wear a size 7 and got the S/M. The socks are comfy for socks, not itchy at all and no blisters. I also like the low cut, they fit just above my shoe and always stay in place. Yay socks!
