A ride to the other side of the city can squeeze a lot of sweat from your pores, but with the breathable Swiftwick Performance Four Sock, you don't have to deal with pools of sweat in your cycling shoe.

  • Synthetic Olefin fiber dries quickly, breathes, wicks moisture, and resists the growth of odor-causing microbes while also remaining impervious to chemicals and perspiration
  • This durable, versatile polymer that won the Nobel Prize in 1996 produces very little waste during manufacturing, and is easily recyclable to reduce environmental impact
  • Hidden toe seam prevents rubbing and blistering during long walks or runs
  • Nylon toe and heel provide long-lasting durability
  • Spandex in the arch hugs your foot's natural shape to keep it in place and feeling right in your shoe
  • Y-Heel contour anchors the heel and moves with your foot, not with your shoe's collar
  • Lightweight top of foot encourages ample breathability and isn't bulky
  • Double weave on the sole provides great breathability and a little cushioning to reduce impact
  • Compression double cuff doesn't move no matter what you do for training or exercise
  • Four-inch ankle height prevents rubbing from the collar of your running, hiking, or cycling shoe

Good quality!

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

I wear a size 12 shoe and the large size pits me perfectly.
These socks are light weight and are made very well.
Excellent value!

Double cuff.

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

The double cuff defining Swiftwick's Performance line extends the secure compression from the foot up to the top of the sock.

I'm a size 12/46.5, and the XL fits best. Large is serviceable, but the sock's heel cup sits a bit low and extends into my mid foot.

Durable + Compression = Love

  • Familiarity: I've put it through the wringer

Swiftwick socks are fantastic. Nice and snug to your leg, no sliding up and down., and durable to withstand many wash cycles. It is one of those socks that you could feasibly buy 2-3 pairs and rotate those through consistently and not see the sock break down. For those of you that wear out socks and take pride in it... Good luck wearing these ones out... Happy cruising out there!

Perfect Black Sock

    Fit's great, no problems. I'm a US 10 or size 44 in Sidi (w/ less than 1mm before my big toe touches the inside of the shoe using Specialized BG insoles) and the MEDIUM fit perfect with out the heel cup needing to be midway up my Achilles tendon! Will order again when the need arises.
