Gym shoes (for school) that arent big, ugly, and clunky?

mostly because i want to look cute and dont want my feet to look huge, but also because big clunky shoes get in the way of running/exercising, which is the whole point of Gym! are Pumas good gym shoes? or are they like not good for running etc? because theyre the only ones that i can find that arent like, huge and heavy on my feet!
