Shoes are arguably the most important gear selection a thru-hiker will make. Unlike the equipment you carry, shoes directly affect your comfort and stability as you walk. Chosen wisely, they can prevent pain and injury.
In the several years leading up to my first thru-hike, I knew the importance of footwear and focused considerable time on selecting what I hoped would be the perfect pair. I tested dozens of shoe brands and styles. If you were to point to any shoe displayed in an outdoor store like REI, chances are good I wore it.
After wearing so many shoes in those years, I should be a footwear expert by now. I wish that were true, but it's not. At best, I've only become knowledgeable about what works best for my feet.
When I'm asked what shoes I wear on my hikes, I explain my choice might not work as well for everyone. The fit and needs of each hiker are individual.
