I bought these 790s for my first assignment flying C141s out of Ramstein AFB, Germany. I needed something insulated and waterproof because of the weather out here. So far, these have been great flight boots compared to the pair issued to me in UPT. I always have cold and sweaty feet and the gore tex keeps them pretty dry and warm when paired with wool socks. Nice to find a pair of good quality boots made in America.
