I will sometimes go sockless with trainers - but your feet sweat more without socks (well the socks absorbe the sweat) & therefore it can make the trainers smelly! But I tend to wear the half socks (just upto the ankle) with trainers in the summer.
I'd never go sockless with shoes! I sometimes wear half socks with my shoes when its hot - with trousers or jeans. Other than that I just wear whatever socks I pick out first! Be they black, charcoal, beige, navy...
What I would like to know is would/does anyone wear really loud/bright socks - such as Ralph Lauren, Duchamp, Paul Smith??
