I see the benefit of bike shorts. I even see the benefit of a jersey though I can't stand tight fitting clothing so I just wear sports shirts, but socks?
I wash my socks every day. I have about 30 pair of them. I put them on, wear them at work 10 hours or so, swap from my work boots to tennis shoes, and ride after work. When I get home, I'm typically barefoot in the summer so the socks are in the clothes basket with the rest of the laundry.
