I am 5'3, and I barely make it for a size 5 (US), I cannot find any boots that fit me well. Last year I bought a pair at the children's place because I could never find in any other store.

any sporting goods store should help you out. If you live near a boardshop that sells snowboards, they'd hook you up with hella nice snowboots. I'd highly recommend getting snow gear during the summer, because that's when they mark down the prices VERY low, making room for the new merchandise.
The best snowboots I've had are DC's. They know quality fairly well, but it honestly depends on the model0
