    Let your feet breathe.

    Comfy feet are the foundation that a good ride is built on, so finding a killer pair of socks is more necessity than luxury. Castelli's Lowboy Men's Socks fit the bill--and your feet--with a cooling, supportive design that uses Meryl Skinlife fabric to make sure your ride stays on solid footing. Meryl is highly elastic and breathable, so it will help reduce fatigue and swamp-foot syndrome, and Castelli's midfoot support band helps increase support and long-distance comfort. Even the cuff is finished with antimicrobial silver threads, which fight off bacteria to keep your feet smelling as fresh as you feel.

    Nice and thin, but with thick logo

    • Familiarity: I returned this product before using it

    I like that this sock is nice and thin. Only 19.7 grams!

    What I didn't like about it was that the logo in the midsection of the foot is thick and puts unnecessary pressure on a band of the middle foot. After testing for just 2 minutes, the logo left an imprint on my foot. This logo is purely cosmetic but it reduces the comfort of the sock.

    Great socks, so very thin.

      Awesome socks. They're so thin I can actually feel the breeze on my feet while riding. I ordered one pair but will get a few more.

      The only reason I don't give them 5 stars is that they still show above my SIDI bike shoes. I was hoping they were low as in no-show. Just my personal preference and absolutely not a knock on the socks.

      I have some smartwool lowcut socks (something like the Ultralight micros) that are completely covered by my SIDIs which I found less comfortable than my higher castelli winter socks because the tongues of the shoes cut into my feet every so slightly. But if you like noshow, maybe you could check those out
