I do it. That's the main reason I buy k-swiss is because they are not covered with flashy logos or obnoxious colors. Personally I feel that they look quite sharp with a pair of khakis or jeans - however, if you wear a polo shirt and a baseball hat with them, you have to be careful not to look too much like a football coach on the sidelines. I find it's a better look for me to go with a longer billed cap - and maybe a long sleeve denim shirt - going for that fisherman, outdoorsy look (like the old J. Crew catalogs).
