Danner Combat Hiker Boots 29cm (US 11) Developed for US Special Forces, the Danner Combat Hiker is a tactical boot that offers excellent durability and comfort even in harsh environments. Originally designed for soldiers requiring mobility in mountainous terrain, it features a rugged full-grain leather upper and a Vibram outsole. It provides reliable grip even on steep terrain. Size is 29cm US11. I have used them a few times after purchase, but I am selling them because they don't fit and cause blisters.
