Finally found great socks - I was worried about one size fits all, but they are perfect size - I wear size 7 shoe and slightly wider foot. I prefer thinner socks and these are just right, not junky thin! The big test- how do they hold up after washer and dryer? - PERFECT!! DID NOT SHRINK, no piling, and no fading!! I have paid high prices for sporting brand name socks and all have been disappointing in some way. Plan to buy more of this brand in more colors.
