More performance, less tan lines.

If you're tired of the tall-sock trend and the embarrassing mid-calf tan lines that accompany it, you'll love the Swiftwick Aspire Zero Socks. They're the antithesis of tall with a barely there, ankle-bone skimming fit that will peek out of your shoes just enough to add a splash of color to your day and protect your skin from any shoe-edge chafing.

  • Y-shaped heel contour
  • Arch band midfoot support
  • Low-profile height
  • Made in the USA

My feet

    are a little less sweaty now, or at least I fell it less. Ive been slowly upgrading my socks from just regular cotton to performance and I like these the best so far

    These socks are the BEST!

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

    These socks are by far the best socks that I have used. I used to have issues with blistering while long distant running, but these have solved that problem. They are very durable too. My last bundle of running socks lasted around 4-5 years of regular use. Also one of my favorite things about these socks is that they don't seem to stretch out. Its like you have that new sock feel everytime that you put them on. At a size 11 running shoe, the larges are a perfect fit for me. It's also very awesome that they have so many colors. We got girly colors for my wife, and I got normal colors so that we don't have issues when doing laundry.

    When will you get the grey in L again?

    Hard to only buy 1 pair...

    Just like the other review from Matt below, if you only buy one pair, you're going to be doing many loads of laundry. Hands down my favorite socks for keeping my feet happy and dry whether its cycling or running. Do yourself a favor and just get two or three pairs right off the bat :)

    use them for cycling - these fit really well without too much compression, or slippage. buying more of these !

    Thanks for the review! Super helpful to get this feedback out to the community.

    The only socks that I use now!

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

    I've used swiftwick socks for the past 3 years almost exclusively. I searched and searched for the best running sock I could to avoid blisters while running. Probably tried 15 different socks before I discovered these, which was ridiculously expensive to figure out. I just needed something that wicked well to keep my feet dry, fit snuggly even after lots of use/washes, and something that had the right amount of slip inside my shoe to keep my feet from blistering.

    After three years of high usage, I finally had one pair wear out. I also love these for cycling. I recommended these to one of my buddies to try for long distance hiking, and he also has fallen in love with them. I can't recommend them enough.

    • 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

    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
