I'm returning to update this review.  These socks don't hold  up and have sprouted holes on the heel bottoms.  They are not the quality I expect from the brand. I like these as they seem to run a bit small and my foot is about a 7 or 7.5 length.  Minimal cushioning and best for warm weather.  I wear these under running shoes with mesh type breathable tops and it's a good combo for me.  Wash and dry fine and can be bleached.
