/fa/ - Fashion

So I've just been offered a new job and I need a pair of trainers/shoes I can wear. I wore my brown brogues to the interview (I have a black pair as well) and the boss told me I didn't need to dress as smart. So it's sort of smart-casual but more on the casual side (engineering firm). I showed him my GATs and he said they'd be fine, does anyone have any suggestions for relatively "smart" casual shoes I can buy? I was thinking desert boots or something? Maybe not something super preppy like boat shoes or loafers though.
