Cycling socks redefined.

The Cyclismo is the result of DeFeet setting out to create the ultimate "modern cycling sock." In other words, DeFeet combined its best materials and innovative fit technologies together in the form of a streamlined, comfortable, and versatile cycling sock design.

The Cyclismo socks were developed in conjunction with a DeFeet-sponsored professional athlete's input, which is why they feature a specific lightweight material and innovative fit attributes. The material used to create the socks is a polyester blend known as ThermoCool, which provides exceptional moisture management, breathability, and soft next-to-skin comfort throughout a wide range of temperatures.

Starting with the toes, DeFeet applied its signature No-Feel-Toe-Seams. This is a construction method that tucks in the seams to ensure that your toes remain comfortable and chafe-free throughout the duration of your rides. At the metatarsal region, "Meta-pads" were built into the Cyclismos. Essentially, this is a lightly padded section at the ball of the foot, which increases comfort through its lightly cushioned composition directly above the pedals.

Reinforced heels add to the socks' overall durability, and lightly compressive five-inch cuffs provide both support and additional coverage around your ankles and lower legs. Additionally, the Cyclismos are left- and right-foot specific.

The DeFeet Cyclismo 5in Socks are available in four sizes from Small to X-Large and in the colors Black/white stripe, Black/red stripes, High Vis/black stripe, Hi-Vis Pink, White/red and blue stripes, and White/black stripe.

Not very sexy, but...

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

Hazard orange in motion, probably a good thing. Could be a bit more flashy, but they fit great & have held up well over time.

I got hit by a car over a month ago, should have been wearing these! Fortunately, I was able to walk away...

Get many

Light sock for cycling, love the quality and look, and especially the comfortable feel.

Nice Fitting, Look The Part...

  • Fit: True to size

I prefer DeFeet or Rapha socks for cycling. These socks are nice but I prefer the feel of the "Aireator" sock over the "cyclismo". The 5" height is perfect, fit excellent and very durable sock. Work well for a large range of temps, but not for winter. The waffle pattern of these socks is not as comfortable for me as wearing the Aireator style and the extra padding in the ball of the foot on the Cyclismo starts to bother me on long rides. Overall, still one of the best socks out there.

sick awesome socks

  • Fit: True to size

These socks I ordered due to the decals on the new bike. The colors matched perfectly well. Sort of surprisingly it also rides great on long and short rides. Strong material, easy to pull on and off.

Socks wear out FAST

    I wore these socks a handful of times and found my big toe had already ripped through the front. If they were more durable they'd be great, but not worth the money when they're not wearable after a few uses.

    Great fit, easy to wash, comfortable to wear, quality fabric, durable, all adding up to my favorite socks to cycle in.

    The best sock with great comfort!

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

    I love DeFeet socks because of the great comfort they provide. This sock offers a thin, lightweight solution for cycling. It helps to add no seams and avoids any unnecessary discomfort. Definitely my go to for cycling socks.

    Fave cycling sock by far

    • Familiarity: I've put it through the wringer

    These are my favorite cycling socks by far, and I've even started using them for running, ice climbing, and skiing! Great durability and breathability.

    My Favorite Bike Accessory!

    • Familiarity: I've put it through the wringer

    These socks are my favorite because they're breathable but not too cool, so they are a great versatile item to have in your wardrobe. I also love all of the colors that they come in -- pink is the best of course! I love wearing these socks and they definitely make you stand out.

    Size: I'm a US 9.5-10 shoe. Should I go with M or L in this sock?

    Best Answer

    The large sock will fit you best.

    Maybe the best DeFeet socks?

    • Familiarity: I've put it through the wringer

    I'm a DeFeet fanboy. I probably have more DeFeet socks (all models) than most people. It's a problem. I'm not getting help, SO STOP PUSHING ME MAN!

    Sorry for the outburst...


    These seem to fit a bit better, and are slightly more compressive, and that's a good thing. Plus the 5" cuffs. Sh*t just looks pro, which is half the battle anyway, right?

    And they are thin! No issue wearing them with the tight road shoes. You listening Hincapie?

    I'm amassing another CC order right now, and a couple more pair of Cyclismo socks will be on that order.

    Love these bad boys

    • Familiarity: I've used it several times

    I use these for road riding in SoCal and I have to say after being recommended by a friend and finally getting a pair I truly do love them. No seams, no discomfort, and also reduces hot spots if you get 'em. Great sock--I highly endorse.

    Love em

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

    With a drawer full of cycling socks, these are the ones I always grab. Love the taller cuff and pad on forefoot. Absorbs a fair bit of road vibration. The seams in the toe box are great. Never had a rub or any discomfort with them!

    How is the fit? If the shoe size is men's 10, which is better M or L? Don't want bunching if Large is too big, but don't want to small w/ the Med. Thanks

    Perhaps my favorite socks

    • Familiarity: I've put it through the wringer

    The Cyclismos perform almost like a base layer for the foot, consistently wicking away the moisture that's derivative of shoe covers, friction, or just plain-old heat. As a result, I always stay dry, regardless of the conditions. The feel across the mid- and forefoot is exceptional, and the socks' hold on the legs never waivers over the course of a long ride. Easily, though, my favorite aspect of these socks is that the seams are structured externally. Robert Forrester really said it best in that socks have been historically designed counter to logic. With external seams, DeFeet has righted this wrong.

    Those socks will make you 2 mph faster

    • Familiarity: I've put it through the wringer

    Just kidding.

    I do love those socks though. Very comfy, warm when you need this, ventilated when you need that. Nice stretch around the foot and the little metatarsal pad seems to do its job. No hot spots.
