These socks were exactly what I wanted in a running sock. I hate wearing socks, so finding a sock that doesn't irritate me is a challenge. Up till now, I've only been able to stand the ultra thin Asics no-show socks. But since I can't find them anymore, I decided to try these. They are so thin and breathable and they don't slip down in my shoes due to the well constructed heel tab. The toe fabric remains roomy throughout my workout. They are a little pricey, and I wish they came in white in my size. But I am happy they have a women's size large that is roomy and breathable.
