Ugh, I love Smartwool socks, but these were a huge disappointment. They fall into my shoes within minutes, no matter which shoes I'm wearing. Maybe this pair sized small because the fit of my other SW socks is perfect. I like the thickness and color (pink!), but sadly, this pair is going to the thrift store. :(

These are the perfect socks. They are comfortable and durable and they stay on my heel!! I ordered one pair at first but I'm definitely going to get more.

I bought this sock to wear running, at workout class, and to work (I like things that work in any setting!) I really like this sock - it is soft, comfortable, easy to wear. It is a little bit warm under sneakers on a warmer day, I'd go with something lighter if you're not looking for a winter sock.

These are my favorite running socks! I'm admittedly a bit of a merino wool fanatic, but only because I'm convinced that it is the best natural fiber in terms of texture, superior temperature regulation, durability, and odor resistance. This sock matches up on all fronts. They are super soft, do not get smelly after any length of run, wick sweat away from my feet, and don't wear through as quickly as my cotton running socks.

My street shoe size is between 8.5 and 9.0, and the mediums fit perfectly.

When I first put these on, the fit felt incredible! However, within the first wear, fuzz had formed all over the toe and heel of the sock -- BEFORE I had even washed the rocks. Already looking scuzzy within the first wear -- no bueno!
