I'm a teenager with big feet and I just want to know if there are any cool websites or stores (preferably in Canada) that sell women shoes in size 13.

I wear a 12 or 13 too :) Try Gothicplus.com and Shoeoodles.com - you can filter by size on both. And a woman's size 13 is a mens 11 btw, so many unisex styles and sneakers can work for you too.

Zappos on line. Call your feet aristocratic not big. Many long feet are elegant. Always think of your feet as such and give them the best that you can.
