I wear a size 14 wide and have a heck of a time finding boots and insoles. I have found that most company's "large" insoles aren't large enough for my boot. That being said, Superfeet makes their Orange and Merino Wool in a large enough size. I run the Orange in my warm weather boots for hiking and early season and the Merino go in my cold weather gear. I have tried numerous insoles and these have been the only ones I have had true success with. That said, I haven't tried the Lathrop and Sons yet.
