These are some serious boots. Waterproof, sturdy leather, great traction, etc. The tongue is stitched to the rest of the boot so water can't seep in. The padded ankle is definitely a nice touch. I'm very pleased with the quality overall and would definitely buy another pair when these eventually wear out.
For sizing, I typically wear a size 12 for sneakers (size 11 for Chuck Taylors). I ended up buying size 11.5 and they fit comfortably with room for a pair of thick socks.
