Hello folks! First post here on Permies, and I was excited to see the vegan subsection on here.

These boots are great. I've been vegan for quite awhile and have always been in search of a strongly made boot. I work in construction and these hold up. Originally designed as a combat boot, they breath and are comfortable. Even have a vibram sole. Garmont also makes(or at least used to) a hiking boot with a very similar design and less military looking.
The one I linked is made in both black and tan. Be careful if you look for these boots elsewhere. For years it seemed like they were a vegan boot and then the tags stopped saying synthetic leather, so this site has them special ordered from Garmont. They are not cheap, but last a lot longer than any other boot I've tried.
Hope this helps!
