Looking down and not wanting to see more than two colours, or any weird or funny looking things, especially if they don't sit right with whatever pants I am wearing.
Big bulky shoes with thin ankles in shorts just look so funny to me, but I guess that is why I wear long pants most of the time anyway.
There was a time when I would put in black laces and colour the stitches black too on some classic colour Vans, but I think that madness has eased a bit now.
Eras (no show socks) in 874 cut off shorts right now with it being quite warm.
Old skool, Sk8 hi, Half Cabs with long pants, as long as the pants sit down over the shoes - 874 Dickies 24/7 anyway so usually nicely covered at all times.
