Try TKBoots.com Even though the site says they are out of production for the time being, they still may have some in back stock. I sent them an email recently to find out if they have any backstock / cancelled orders and he said they have a bunch, including a size 14. These boots run a size large (long) so if you're a 15 their 14 may fit you well. Give it a shot! They are a bit narrow. I'm a size 11 and bought both a pair of 10 and 11. The 10 fit me perfect and the 11s fit well with gel inserts and thick socks.
