The sole (and overall fit) is wide. Which is great. Traction was OK on all surfaces, but soon the tread was thinning and grip was falling. After just 1 year of use the tread is about half of what it was new. The D rings are a bit iffy so I have always been carefull with them. Metatomical Footbed Design: This internal support mechanism is anatomically engineered to provide excellent arch support and cradle the natural contours of the foot. For me there was no break-in time. This may vary depending on invidual preference. They did soften up quite a bit by day 2. The leather upper of the KEEN Pyrenees is not something to be downplayed, as we affirmed on our lab and hike tests that it’s the star of this KEEN pair. With that, we declared it the greatest leather boot from the brand. Resistance to water and abrasion go hand in hand with this material, so our feet are 100% protected. We’ve turned to nature to eliminate pesticides and biocides from going into the environment.

The boots are roomy, especially around the toebox, which allows your feet to spread out. This makes them a great option for anyone with wide feet. Initially, I found them to be almost too spacious and airy, but after several walks the leather moulded to the shape of my feet and this became less of an issue. After testing the Pyrenees on several rainy walks, the boots remained watertight (a combination of the Keen.Dry waterproof, breathable membrane and PFAS-free water repellency). The high ankle support and tight lacing system mean that gaiters can be easily and securely attached to the boots, offering further protection in wet conditions. The boots proved to be watertight on test. Joe Pontin / BBC Countryfile Magazine Do they grip well? Overall this is a solid boot that really can do anything. Very pleased with these boots. Highly recommended.Note: Make sure you lace these up correctly the first time you wear them. The laces do make light grooves in the leather tongue, so the way you lace them up the first time is the way you will have to lace them up every time. The reason for the need of a 100% leather boot is that most of my geocaching is done in the deserts of California. I’ve found that non-leather boots and shoes let in an exorbitant amount of dust and dirt, either over the top of through mesh that is so popular on shoes these days. Also, here in SoCal, there are fields of foxtails and a full-leather boot is the only thing that will keep them at bay.

Pros: 1) sole has good feel==boot seems very stable on uneven surface you can feel the lugs doing their job- 2) tongue and fit around instep feel great- 3) i am hard on boots and the protection on toes does great 4) water proof Waterproof, during my first excursion through the woods, I did cross a stream and my feet stayed dry. I personally love the wide cut in the boot. Sometimes I refer to my feet as flippers and this boot is great for me in that aspect. KEEN Dry: A proprietary waterproof, breathable membrane that lets vapor out without letting water in. Tanning leather is a dirty process. That’s why we source our hides from Leather Working Group-certified tanneries that use processes to reduce chemical use and the impact on our watersheds. Eco Anti-OdourThe Keen Pyrenees is a classic leather trail walking boot which blends the traditional all-leather construction with the always popular wider fitting of the Keen brand. Modern waterproof/breathable technology from the KEEN.DRY membrane ensures your feet stay dry and comfortable all day and the dual density EVA footbed provides exceptional cushioning and comfort. Keen started making outdoor footwear in 2003, and is probably best known for its sturdy and practical walking sandal. The brand is also renowned for producing walking shoes and boots to support those with wide feet thanks to its boxy designs. Not just a summer option though, the brand makes walking boots and shoes for all seasons. On test here is the Men's Pyrenees hiking boot - an all-leather hiking boot designed for long trails. First impressions Our top-rated Targhee collection is available with a wide range of options to suit any trail. The Targhee EXP waterproof mid boot gives you ample support with uppers built to resist everything you can put them through. Performance mesh uppers provide great ventilation, but easily fend off scuffs and tears. The Targhee III waterproof boot delivers that same fit in a low design, for mobility on a wide range of terrain.

Breaking in the boots took a couple of days. I had a bit of a pressure point along the tongue, on the top of my foot. By the end of the second day, that disappeared completely. A few more days wearing the boots, I knew I had a real winner on my hands...er feet.

Initial impression of the Keen Pyrenees (Bison)- Build quality seems pretty good. No blemishes in the leather, stitching seems of decent quality, and overall my first impression of this boot seems quite favorable. Our top-rated insulated hiking boot is the Summit County Waterproof boot, which has waterproof leather uppers and targeted insulation. You get 300 grams of insulation around the main insole, with an extra 150 grams (for a total of 450) around your toes. The waterproof, breathable membrane lets moisture escape when your feet warm up, and the outsole is designed specifically for icy conditions. Got these boots because my friend had a pair of Targhee II's and loved them. I looked at the Targhees and decided I wanted a full leather boot with more support. When I was shopping for new boots I tried on several pairs and brands. I love the way Merrell boots fit my feet, but just couldn’t find anything in their line that I was happy with (and willing to pay for). When the salesman suggested the Keen Pyrenees, I was a bit turned off by the styling. They have a bit of a funky look about them. But the second I put these boots on my feet, I was sold!
