I've been wearing jungle moccasins for a long time. With the latest pair, Merrill seems to have changed the last one the shoe is built on and it was way too tight. I usually wear an 11 in these shoes so I ordered 11.5 and they fit perfectly!
Pros
Pretty decent shoes around
Cons
This shoe is not true to size. They run from 1/2 up to a size. Expect high arch support.
