Over time I have become aware that warmth and comfort do effect performance. This seems to be especially so when it comes to outdoor winter weather, but applies to gym use and warm weather as well. These socks serve both purposes well. But what they also do (which is very rare) is recognize that there is a need to design the left foot differently than the right one as well. If you try a pair, I'm sur you will agree. Of course, unless you're a Crimson fan, they should be from another school, and Yaleies should not use them at all.
