These Swiftwick Aspire Zero Socks are the shortest socks we offer. If you hate the tall sock craze, these are the antithesis. The cuff will ride right at the top of your shoe, and you won't have any funky mid-calf tan lines.

The Aspire Socks are created by a 200-needle machine process that yields a high density, seamless knit fabric. The process allows variability in the finished knit of the socks, as different parts meet different performance requirements. For example, the cushioned footbed gives way to the thin channeled upper -- both components playing a crucial role to increase your comfort. When you slip into a pair of Aspire Socks, you'll immediately feel that they're tailored for your feet. The arch band offers snug support in the midfoot, and the Y-shaped heel contour assures no bunching or overstretched feeling in the back.

The dense nature of the material all but guarantees durability when combined with the abrasion resistant properties of Olefin, one of the prime components of the foot of the sock. Olefin is a lightweight polypropylene fiber that Swiftwick sources from US manufacturers. Then the socks are created in Tennessee in Swiftwick's own factory, where they can oversee every step of the process to ensure tight quality control. The Olefin wicks like crazy to keep your feet dry, but removing moisture from your skin is only half the story. Olefin is also hydrophobic and will not absorb water, so the moisture transfer is complete all the way to the outside of the sock. You'll stay dry, comfortable, and blister free since the socks move with your feet and minimize (or eliminate) abrasion against your skin.

Several knitting patterns in the footbed and cuff give the Aspire sock a compression nature which promotes blood flow in the feet, improving flow throughout the lower legs. And as you might guess, improved vascular performance means reduced fatigue and speedier recovery. The Swiftwick Aspire Zero Socks are available in Black, Grey, and White and come in four sizes from Small to X-Large. It's worth noting that the fibers used in Swiftwick socks are colored during their creation. In comparison to socks that are dyed after knitting, this makes Swiftwick socks stronger and more durable.

Swiftwick Zero Aspire Socks

  • Familiarity: I've used it once or twice and have initial impressions

Received my order late yesterday, wore them on my morning TT. Excellent fit, no chaffing, extraordinary feel of quality. Feet were dry and comfortable after 25 miles of riding.
I have a high arch and many socks slip down, not these. Very pleased, will see how they fare after being washed

Best Socks I have worn

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

How much did I like them? I bought 16 pairs and replaced all short active socks that I owned so that they would all match. I hope that I don't need more. If you run, ride, or just like short, light socks, buy them, in bulk, you won't regret it
