I see a lot of people wearing cycling socks for running but I don't not like the feel. I have worn smart wool socks and loved it though. Actually my favorites are these new TEKO Merino Socks I got at the REI clearance, they are a midweight a little thinner than Smartwool cycling socks. I personally do not like thin socks, I think it is personal preference. I also cannot wear road shoes, I wear light weight trail runners even for asphalt which makes my running co-workers balk at me.
