For 13 years in law enforcement I've tried all types of boots. For the cop that does not want to feel like he has WWII issue leather blocks on his feet, this is what you want. They feel like tennis shoes, but are constructed of incredibly durable materials. The quick-lacing system is solid, and I haven't once had to re-tighten them mid-shift. They are not waterproof, but I don't wear waterproof boots anyway, because they don't let your feet breathe. These breathe exceptionally well, the best I've ever seen. There was no break-in period whatsoever. Buy these boots.
