Familiarity: I've used it once or twice and have initial impressions
I'm not someone who usually buys running socks, but figured what the heck. I've used these once (for an indoor/treadmill run) and I love them! I was really concerned about the grey color because I tend to get Athlete's Foot when wearing colored socks, but no problems at all! I wish I would have bought more than one pair.
