A Goodyear welt is the foundation of pretty much every pair of solid footwear you will ever own. Wolverine employ this technique in every pair of its vaunted 1000 Mile boots. Not only does a Goodyear welt allow for a boot or shoe to be resoled time-after-time, but it also adds comfort and strength.

Check out the rest of the video to get a better look at the work that lets your boots keep keepin' on.
