I have two pairs for Lems boulder boots one all leather, one cordura and synthetic leather that are 7-8 years old and they have actually held up amazingly for being so damn light weight. I wore out a pair of Blundstones and my thinking is to wear the lems out and replace both types of boot with some jim green barefoot stockmans, those with my Courtney Selous should give me two really good options that aren’t overlapping in function
