Hey dude. I have a buddy of mine who recommended the Forzani Tech Shop here in Calgary. It's a running store but they are open to ordering in ball gear. I went and checked it out, and they have full access to Nike Canada's basketball footwear. When I went in there i just let them know that I needed some ball shoes and let them know what style I would like to get and they ordered it for me. Took about 2 weeks tops. It was sick, saved me from having to order online and deal with that mess. The location I went to was on 19th Street and Northmount Drive in the N.W. Calgary. The guy that was there told me as long as it is available in Canada in that size they can bring it in. I'd check it out my buddy is a size 15 and they got his shoes to him in no time.
Hope this helps. Best place I have found in town to get a size like that.
