Note: This is not a thorough review. Just a preliminary review in hopes of helping others. Many years ago, when I first discovered Merrell shoes, they were the perfect fit for my feet. Ready to go, right out of the box. Not any more. Merrell has opted to add high arches in their insoles, which are extremely annoying to me. And for the life of me, I can't understand the popularity of such high "arch support", given the fact that our weight, when walking barefoot (naturally), is dispersed primarily to the balls and heels of our feet, not the arches. These shoes fit my size 10.5 average width feet perfectly, much like Oboz shoes, with no annoying high arches. Over the years, I have worn shoes from Merrell, Vasque, Hanwag, Asolo, La Sportiva, Oboz, Timberland, Adidas, Lems, and more. After Merrell changed the way they make their shoes, Oboz quickly became my favorite. Perfect fit right out of the box, ready to hike. I have never owned, or even tried on a pair of Keen shoes, until today. I made the faulty assumption that their shoes were just too wide for average width feet. But this shoe caught my eye, so I thought I would give them a try, and I am glad I did. PERFECT fit, comparable to Oboz. And the sole appears to be a very solid sticky rubber. Time will tell how they perform on the trails.
