I ride a ton and go through a lot of socks MTBing and road cycling. I finally found a sock that not only fits well but looks great. A lot of white socks turn off white or yellow after a month or so. This sock looks the same as the day I bought it so it always matches my shoes. While mountain biking it not only stays up and doesn't sag but it doesn't collect a crazy amount of dirt. If I could afford it, I'd buy up the entire factory of these socks. And yes I wear them even when I'm not riding a bike.
