Wearing wedges in 8th grade?

ok i love fashion heels makeup getting my nails done i'm a complete girly girl. i even did 3 fashion shows so i can walk in really high heels n i love it. I have really flat feet so i cant wear flats unless i have these cushion things in them. but i dont want ppl to think im trying to act older than i am because i'm wearing wedges. I would never wear heels to school just wedges. n i plan on wearing them every day except when i wear sweat pants i would wear my puma gym shoes or something. so what do u think should i do it or not? I dress very conservative so it's not like i'll look trashy or anything. Just tell me what u think please :-)
