This shoe is awesome. I've waited till I had this shoe for a year till I wrote a review so that I could determine the longevity of the 1520. I originally bought it thinking I was just going to try it on then send it back. I heard a lot of bad reviews about it's fit and such, and I thought for sure I was going to go with one of the other 3 shoes I'd also bought and had sent to me. (I have size 15 feet, and no stores carry my size) Once I got the 1520 on my feet, I didn't want to take it off. I sent all the other shoes back and kept this one. It's SO comfortable to walk around in. The Vibram soles give it a lot of good traction. The tongue is fully gusseted, which means that water won't be entering through the tongue. I read some reviews where people complained that the boot wasn't waterproof because water could still enter through the top of the shoe (like, where the foot goes in?). I fear these people have a bad conception of the laws of physics. So far, i haven't had any water problems with these shoes. I wear them every day, and they're still very comfy and looking great.

One thing I want to add. A lot of people said these shoes were off in size. This is the main reason I thought I wouldn't like the boot. I have 15D feet, and my shoes fit perfect. Do yourself a favor and try them on for yourselves. If they don't fit right, send them back. But if you're like me, you probably won't want to take them off.
