I used your socks as part of my training and racing in the 2008 Great River Ragnar Relay. Our team was made up of six geriatric runners. I ran literally hundreds of miles over the summer in your socks. We each ran three legs varying in distance from as little as three up to nineteen miles. During the relay I wore your socks for my first leg of fifteen miles. I never once had any blisters, rub points or discomfort from the socks. I liked the compression areas on long runs from a support perspective. In hot weather I did find your socks to be quite warm and would have preferred them to be a bit lighter, however if weight is a trade off for support, I’d retain the weight.
