I have the Pegasus Airboots and I really like them, but I have not noticed a HUGE difference in the heat trapped, or the sand that gets in, which I also hate. I also don;t think they give as much support os some of the others, but they sure are easy to use, and will protect frm dings and sand burns. In fact, when I bought them at RTTH a couple of years ago, the rep told me they were looking at making some with skid plates on them for reiners.
