Hello, i'm having a bit of a problem finding clipless MTB shoes which fit me, I'm 6'3", and have size 15 UK, 16 US or 50.5 EU feet. As you can probably imagine, there aren't many shoes around with this size. If any of you know of a set which could fit me, please comment down below.

A quick search shows Lake, Shimano, Louis Garneau and Pearl Izumi all make size 50 shoes. Will they fit ?, you have to try them on. Some manufacturers are sized small, the Lake winter boots I just purchased are a 47 when I use a 46 in Shimano. I'd do the research from these companies, add in Mavic, Giro, Specialized as well. Than find a good LBS, see if their website lists inventory, etc... and pay a visit.

Note that it's a crap shoot buying shoes via mail order as I discovered with the Lake shoes I purchased. I typically go to the LBS for shoes.

Shimano make them, I have a set, they are narrow though. I only use them for my trainer at this point since I ride flat exclusively.
