Do they even make women's snowboard boots...
Do they even make women's snowboard boots bigger than a size 10? Or do all manufacturers only go up to size 10 in women's boots? It's not looking like it, from my research and I've only ever bought men's boots anyways. That's so lame if so, but I'm used to it. I'm ALWAYS stuck buying men's gear because I'm a 6'2"-6'3" woman.
Check out the DC Phase womens boot and the Burton Mint. They are made in larger sizes. www.the-house.com allows search by size. hope this helps.
