The Swiftwick Aspire Four 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 "four" in the name refers to the four inch cuff height. This height makes them feel great in inclement weather when a bit more coverage may keep grit and dirt from falling down into your socks as it gets thrown up from the front wheel. In addition, the taller cuff height, along with the multiple knitting patterns in the footbed and cuff, adds to the compression nature of the socks to promote blood flow in the feet and lower legs. And as you might guess, improved vascular performance means reduced fatigue and speedier recovery.

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.

The Swiftwick Aspire Four 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.

  • 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
  • Women-specific design features a narrower foot to match your foot shape
  • Seamless prevents rubbing and blistering during long rides or runs
  • Olefin toe and heel provide long-lasting durability as well as great breathability
  • Nylon and spandex arch hugs your foot's natural shape so it doesn't move as you exercise
  • 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
  • Thicker Olefin sole provides extra breathability and a little cushioning to reduce impact
  • Compression double-layer cuff doesn't move no matter how your train
  • Ankle height with four-inch cuff prevents collar rubbing from running, cycling, or golf shoes and help deter chain-to-ankle contact

Can't Go Wrong With These

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

You can't go wrong with these socks for everyday riding. FIt is nice and supportive, these won't slide around on you. The material doesn't get smelly as fast as others which is always appreciated. They do feel a bit thicker than other summer socks I have but that doesn't seem to affect breathability, they wick sweat fast.

Fit is true to size, although since they are supportive/compressive there's a chance they'll be too tight if you have wide feet.

Made in the USA and a solid satisfaction guarantee make these even better.

Best cycling socks

  • Fit: True to size
  • Size Bought: Large

I have been riding for many years, and Swiftwick socks to me, simply, are the best. Carefully thought out and designed, and produced.
Nice and tight, good support, feel great...and many many designs to choose from. Not some goof-ball look....
Many sock lengths to choose from. Buy em !

Keep your feets happy

Good socks that last and last and last...... They are great for when you are going to be working hard and sweating a lot. I wear these for all my rides and my training sessions as well. Nice socks

Great riding sock

  • Familiarity: I've used it several times

I give these socks 5 stars. They breath well and fit snug with no bunching. The material below the ankle is lighter than the ankle cuff that aids in the cooling of these socks.

Always choose Swiftwick

  • Familiarity: I've put it through the wringer

I love these socks - this is all I wear. This is a great length for cycling and trail running. I bought 5 pairs in this same style!

Will buy more

  • Familiarity: I've put it through the wringer

These socks are great. The width is designed for women or just those with narrower feet. If you have average or wider feet check out the Swiftwick Performance Four socks. To start, they are super comfy and the toe seam is hardly noticeable. Some socks have an annoying toe seam that causes pressure points, these do not. They are breathable and do a good job wicking moisture to keep your feet dry, as the brand name implies. They provide some compression for the foot/ankle/calf and they seem to help stabilize my ankle a bit because of this. I use them for mountain biking but they seem like they would be good for any physical activity. Durability is good so far. Fit is true to size. I plan to buy more.

Thanks Brock. This was the most helpfull review on here. I completely missed the part in the Swiftwick description stating that this is a narrow womens specific design. Heading over to the "performance" model now per your recommendation!

The best yet!

These socks are made to fit perfectly. The knitting is zone specific and assures no slipping or bunching at all. My gripe with lesser socks is that knitting bead-seam just above the toenails that can promote discomfort on long rides. Swiftwicks have figured out how to make that seam, seamless! They are a bit pricey but you will soon forget that when riding with these. Oh yes, they last and last.

Oh yeah!

  • Familiarity: I've put it through the wringer

Maybe the best? At least as good as Assos, definitely better than Defeet. The only other sock that stands out in my mind as competitive is the Giro Hrc Team. Stay tuned for updates....

The best

A-z this sock is great. Fit, wicking, comfort, durability.

super legit

    The compression on these socks are pretty amazing. It also helps that these socks are comfortable as well.

    Very comfortable & perfect fit.

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

    These are absolutely the best socks I own. Extremely comfortable and the fit is perfect. I had discomfort in certain areas of my feet on long rides for years and that went away almost immediately when I started wearing these socks. I got them in white. Perfection.

    Worth the Money

    • Familiarity: I've used it several times

    Great fit and compression. They feel great on as well.

    New favorites

    • Familiarity: I've used it once or twice and have initial impressions
    • Fit: True to size

    I love that Swiftwick makes its socks in such a wide variety of lengths--I'm not tall, so having the option to get bright, fun socks that don't have a 7in cuff is great. Plus, the mint color I got is beautiful. If I could, I'd probably try to ride in head-to-toe Celeste, but I'll settle for these for now. Fabric is soft and stretchy, and it doesn't bunch over time or take up too much space in my shoes. Stock up!

    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!

    Swiftwick is the third pair of compression socks I have tried (the others were Nike and UA), and these are perhaps better in terms of comfort and dryness compared to the others. The fit is great, it doesn't grab on to the top of the ankle too hard, a feature that I have found to be common among some brands of compression socks. This makes them comfortable to wear for biking and hiking. The best feature is the fact that there is no seam on the toes, which prevents bunching up on long runs (i.e. no blisters).

    I have worn these on 100 mile bike rides and they stay relatively dry compared to regular socks. The socks have just a touch of cushion to them which makes them comfortable to wear. As for hiking, in my experience these are good for going shorter distances.

    NOTE - the term "FOUR" in the product title refers to the length - Swiftwick makes socks from Zero (ankle socks) to I think Twelve (knee high). I saw reviews for other Swiftwick socks where folks complained that they didn't receive four pairs. Thought I'd point this out - you're buying one pair..

    The best cycling sock period.

    • Fit: True to size

    As a cycling sock connoisseur- and frequent purchaser because of that darn washing machine that seems to eat them, I have tried many a sock. None compare to these. Breathable, Comfortable, Wicking, and Compressing. Brilliant socks! And available in a wide variety of colors.

    The best cycling sock period.

    Great socks

    These socks are perfect for cycling. Nice compression around the ankle and no bunching in the shoe. They seem to have the perfect amount of cushion for no hot spots. I have not put them through a serious test yet. But, on a 65 mile ride, my feet were very happy. These are easily the best socks I have tried so far. [ I have tried many.] Sizing was good for me (9=M) and after a few washes the fit is still good. I dry them on a cool setting to preserve the elastic.

    Long-Lasting Socks

    • Familiarity: I gave it as a gift but have feedback to share
    • Fit: True to size

    Just received my third pair of the Swiftwick Aspire Four bike socks. Too many brands end up sloppy and floppy after a handful of washing, the Swiftwick socks are very durable. The fit is also great, they are easy to slip on and have compression feel to them. I have worn them on many multiple hour rides and have never experienced comfort or hotspot issues. I also like the color selection.

    Socks are important, but often overlooked. These do a nice job wicking away sweat and keeping the dogs comfortable. They also come in sweet neon colors. Machine washing is easy and they come clean every time, even after muddy rides. Fit is great, true to size.
