Once you Smartwool, you never go back
Got my first pair of Smartwools 5 years ago and have never gone back to regular socks since. The 'running light micro' is my favorite design. It's no-show and the lip on the heel prevents chafing. The 'light' weight seems to last a few months longer than the 'ultra light' weight socks - I get at least 1-2 years out of mine. I'd recommend the ultra light socks for minimalist running shoes or cycling, though. These are great for everything else - casual, hiking, running, etc! Wonderful product. Fill your sock drawer with 'em!
