I'm 14 and my calves are HUGE?

Okay I might be over exaggerating when I say huge, but they are big. Over the past month I've been noticing that my calves are fairly larger than other girls my age. I have a hard time finding skinny jeans because of them and I can't wear shorts. They make my legs look short and stubby when they're actually pretty long. They're pretty muscular and I'm just getting to the point where I'm sick of them. I know I can't diet because I'm still growing but is there any way to reduce the size just a tad bit? would running help or would it just enlarge them?
