I have a long narrow foot 10 4A and I am able to wear these for activities such as hiking and running without getting the usual blisters. I also wear them to work with business casual attire and on the weekends with jeans.
I have washed them in hot and warm water and thrown them in the dryer without any ill effects. The socks have not pilled with use.
I bought size Large and it fits perfectly.
My sock drawer is full of smartwool socks. Based on the performance of these socks, my so...ck drawer will be refilled with darn tough socks! The smartwool socks tend to pill and wear out in the heels rather quickly. These socks seem like they will last much longer.

I am wearing these socks right now! They run a bit smaller than usual. I wear 7.5 and the M fits just right. My mom wears a 9.5 and wishes she had gotten the L.

I can only speak for size medium of these socks. They fit me perfectly and I wear a 9 or 91/2 womens shoe.

The packaging says for women S (4-6.5), M (7-9.5), L (10-12.5). I discovered these socks a couple years ago and they are awesome! Very comfortable and more durable in my experience than Smartwools. I have yet to have a pair wear out and they come with a lifetime guarantee!
