Good question Tom. I'm really not sure. I am pretty sure it's not black though. I rarely wear sneakers, and when I do it usually means I'm jogging, and in that case I'm wearing white socks but they only come up below the ankle so you can't see them anyway.

Personally I'd stay away from black socks with white sneakers, or really any sock with sneakers that comes up higher than about your ankle. Or just do like most middle age and older guys do and dress like your wife didnt lay your clothes out for you that day
