This is a GREAT boot. I've had to use them all day long in the rain and in blazing sun. Your feet will stay comfy through it all. Even in the mud, they seem self cleaning & maintain a clean polished look. I've ran in them and have never had any problems. Because of the lace and zip, they stay snug and really are wearable right out of the box. The boot knife is handy too! If I had to reach for something negative to say, I couldn't. It was even fast shipping and the company gave me a mail-in rebate for FREE 5.11 socks!
