OK I ordered a few pairs of the smartwool ultra light biking mini crews. I looked at the recommended thorlos, but they didn't have a color I liked. I got a black/grey which will look OK with shorts and shoes as well as with my business casual work wear.
I should put in a word for the vendor, sockcompany.com since I've ordered from them a couple of times before, and they have EVERYTHING smartwool 15% off. They have a huge selection, and in my limited experience, good response.
thanks for the recommendations. I welcome any further comments, as I may end up trying others as well.
