, Buzz here. I prefer a local brand (made near the Portland Airport ) called Danner. They have a lot of different kinds, I've used the Biscayne for many years, it goes up over my ankle, and laces up. Yes, it's gore-tex lined to keep my feet dry - and it gets damp here in the Pacific Northwest.
A few months ago i bought a pair of pull-on Danner boots, it says "Striker Sergeant" on the lable inside. They're also gore tex lined.
Skydrol resistant? I've wiped a little oil, etc off of them. If there's a big slydrol leak i wear my big rubber rain boots.
Lightweight? yes, they are. A set of soles lasts about a year, then i get them re-soled. After 3 or 4 years the leather is kind of damaged enough so that i buy a new pair of shoes. We're up on ladders, down on our knees changing tires and brakes, in and out of the E+E bay or in the cargo pits or stab. compt. And there are innumerable trips up the Jetway stairs to the cockpit. So heavy boots are not a good thing.
Steel toes: i'm not in favor of them. When i was working in Overhaul, doing sheet metal repair in the cargo pits we were on our knees most of the night, the steel toe section digs into the top of my foot - painful after a while.
Oh yes, i wear wool socks too, even in the summer. I'm fond of a brand called "Smart Wool" they're quite comfortable, it tends to be damp here all year long.
