I love Lems, but the trailhead is narrower than most of their shoes. I hoped they would work for me, but they were a little snug in the toe box. I tried these in a 10 And hoped the 10.5 would solve the problem, the length was good in the 10.5. So if you normally wear a 10 and don’t have super wide feet, 10.5 should be your sweet spot. From website: Our most versatile shoe yet, the Lems Mountain Sneaker is our take on a minimalist hiking shoe equipped for any trail, trek or urban travel adventure. With its natural shape toe box, minimal heel drop, and lightweight design, it's sure to keep pushing your boundaries. Whether you're climbing a 14er, going on a bike and brew tour, or even backpacking around the world, the Trailhead will be sure to take you far away from the ordinary. Designed for the trail but styled for the city streets, this low cut hiking shoe will be the answer for your every move. The Trailhead fits narrower compared to our other styles. The Trailhead is built on our MEDIUM Natural Shape last for a more active fit. If you require additional width in the shoe we suggest removing the insole.
