Sky's the limit.

From riding along BC's Sea-to-Sky corridor to pushing up steep Rocky Mountain passes, the DeFeet Skyline Aireator Hi Top 6in Socks keep your feet pleasantly cool in high-elevation appeal. CoolMax EcoMade recycled yarns actively wick moisture to promote evaporative cooling. Mesh ventilation rapidly cools your feet when you're riding long distances in stifling heat. The compression double cuff retains an ultra-secure fit as you grind up steep grades and plunge down hillsides at breakneck speeds. And to ensure longevity, durable heel and toe panels keep premature wear at bay throughout the season.

Great socks

  • Familiarity: I've put it through the wringer

Love these socks! I wear them mountain biking almost every ride. I love the length and that they don't fall down and the colors are super fun.

Aireator Love

  • Familiarity: I've put it through the wringer

DeFeets Aireators are still the best sock out there and how could you say no with the mountain designs on these. Cycling or in everyday life, you're going to stay cool, comfortable and get a lot of compliments on these. I race in them, wash them and am wearing them to work the next week.

Great Riding Socks

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

The sweet color design is only icing on the cake--Defeet has made and continues to make with these socks some comfortable, quality performance socks. Much loved

Love these socks for riding...color is vibrant, comfortable and breathable where they need it. Functional performance sock meets good-looking with some pop.

Socks On Point

  • Fit: True to size

You are not cool if you don't own these socks. But seriously, really fun socks, perfect height, stay in place, comfy and cool. Great color combos, add a touch of visibility to any kit. I am a size 14 and i love that DeFeet's XLs actually fit me. DeFeet + Ridge Supply = Rad.

  • Fit: True to size

I love these socks. I wear them biking mostly but also casually. They are a great fit, stay cool and don't get stinky even if you wear them a couple times. The colors are great, I get compliments every time i wear them

Easy way to add 100 watts

  • Fit: True to size

I got 11 KOMs and 38 PRs when I wore these socks the first time. My girlfriend says I look more handsome. My bros are too far behind me so I don't know what they think. A must buy!

Socks with Sass!

    Needed something bright to spruce up my murdered-out get up. Defeet knows just how to do that. I picked up an "m", wear a 9.5 women's shoe and they're just about perfect. 5 stars, I dig 'em.
