Where to buy size 15 mountaineering boots?

I am doing a NOLS course, and they require double-boot plastic mountaineering boots. I am a size 15, and cannot seem to find any brands that make boots that size. Any suggestions of where to find big mountaineering boots? 

I was in the same boat last year. Had a pair of La Sportiva Baruntse in a 50 that were a snug fit and somewhat heavy on my size 15 feet. Sold those on MP and bought a new pair of G2 Evos from La Sportiva last year. They retail $950 but are now out of stock. They do have the Olympus Mons in stock in a 50 but they retail $1,299 and may not be what you're looking for. La Sportiva is the only choice, Scarpa doesn't do anything in a sz 50. 

What NOLS branch are you doing your course out of? Most branches have mountaineering boots for you to rent. I’m not sure of their size range, but you may reach out and ask them.

NOLS has size 14 to rent, but i think thats too small for me

Try calling IME in North Conway NH. They have a consignment shop and recently had a client find a pair of size 15 boots used.

Was a pair of prior gen G2 SM (incorrectly listed as Evos) in the rare sz 50 on eb last week for $400 that ended without a buyer.  Reach out and see if you can strike an off-season deal.
