I am a former soldier and current employee of Union Pacific Railroad, therefore I really appreciate a good boot. I was excited to purchase 2 pair of Keen boots for work. I really liked this product due to the high quality stitching and the re-enforced toes. I was incredibly disappointed when after only 6 months the outer sole of both pair of boots had completely torn apart and worn through. I contacted customer service regarding the guarantee and asked for a recommendation for a pair with better soles. I received no information back from them and my claims denied. They did offer a 20% discount off of a new pair. However, why would I want to purchase another pair of boots which would fall apart in a matter of 3 months? I serve as a new hire and remote control instructor for the Western Region, I will not recommend Keen boots to any of my students.
