Love, love, love SmartWool socks! I don't wear any other sock when I run. These guys rock! They don't smell, they don't bunch up, and they are super comfy! They have several styles depending on if your a thick sock wearer or a thin sock wearer, I prefer thick. I also love the little extra lip on the back that keep the socks from sliding down and it's also great for catching sweat! I tend to get blisters on my ankle if the shoes are too low or too high, these socks help with that too!
