Got my Crocs hikers couple days ago and tested it in the mountains on a casual 6 hour trek. I have to say- they do not need any break-in & they look awesome! Straightoff comfort and every step was soft and nice. Its also got fabric lining insides that keeps your feet warm. The fabric lining also makes it rather awkward in keeping the shoe clean after a long sweaty hike & crocs could ve done more in adding antibacteria properties if they were serious. Every review I ve read complained about the eyelets, they are annoying and I guess Crocs wanted to keep the laces in place with those little jagged hooks on those eyelets, but its absolutely annoying when you want to loosen the boot for some reason. IT IS NOT WATERPROOFED FROM THE BOX- its got a gusseted tongue and some SNOSEAL will make sure everything is well sealed after this. The threads held up even after bashing my boots on sharp rocks-I even scuffed the leather in some tight high paths. What makes this boot hopeless for hiking is- it does not have any ankle support. It looks high, but the eyelets stop so low that the ankle area is not tighten at all and there is absolutely no way because of the eyelets to play with lacing techniques. So what you get is a boot with loose uppers, absolutely ridiculous for hiking boots. Be warned also- that they only come in MEDIUM WIDTH. So if you have wide feet like mine, you will just have to stretch them while walking. I wanted this to work very badly and they look pleasant, but its been relegated to work & urban walk. There is absolutely no way this is rugged
