I'm on my second pair already.
They are waterproof until you wear them out and start seeing holes/tears/seams ripping. They are pretty warm with the right socks, but not so hot in the summer that you feel like your feet are melting. I like them as a great all-around boot.
The only downside is that they did wear out in about a year and a half, whereas I've seen people with higher-priced boots that last much longer. (Could be the way I take care of them)
For the price, you really get a great boot. If you are looking to try a pair on locally, I've gotten mine at Wild West Honda out in Katy on I10.
