I love these boots but I'm not longer a backpacker so have gone to lighter, lower hiking shoes. These fit very wide feet - I'm a EE and they're comfortable. If you know Keen you realize they have a nice roomy toe-box. You can see from the tread on the Vibram soles that these have plenty of life left in them. the Keen website has detailed info on this boot: https://www.keenfootwear.com/products/mens-targhee-ii-waterproof-cascade-brown-golden-yellow From REI website: https://www.rei.com/product/772930/keen-targhee-ii-waterproof-mid-hiking-boots-mens
