These shoes are light, comfortable and are sold for a good price (Amazon free shipping).
Usually my shoe size is 45 (11UK) but for boots and sporting shoes it is safer to have some more space for the feet and I ordered the 46 (12UK), so these are a bit large on my feet, but not excessive, and very comfortable for every day use.
These shoes look robust but are very lightweight (comparing with other walking boots that I have). I like the lace system, it's very easy to lace the boots up and it is very easy to take them out.
I don't know if the shoes are waterproof as announced because I didn't take them in to water.
Soles and traction is ok on dry surfaces and so so on wet Portuguese stone sidewalk (calçada portuguesa), for instance the Colorado CAT boots have more slippery soles and one pair of Timberland boots that I have (don't know the model name) are very slippery (like butter) on the same wet sidewalk.
