sandals are fine but they get too much heat here because they are abused too often. I wear sandals or flip flops mostly by the beach, gym lockers, pools, quick errands, etc. A convenience thing really and never with socks
I would not rock them mainly because of the red since it gives it a clownish look. Otherwise, maybe with dark wash jeans and black shirt it can give you that party look. With that said, it depends on the shine of he suede as well..
