I've owned Turtleskins and Listos, and I think the Listos are a WAY better design. The adjustable stirrup keeps them from riding up and twisting when walking through heavy brush, they have much bigger and easier to use zippers, and come in different sizes. You can see in that Turtleskin video, they guy can hardly keep them below his hiking boot top just standing there, which was my experience. But more generally, the Listos are cut better and fit over my Hanwags perfectly, although still a bit sweaty when it's in the 90s like anything else. I wear them in the dead of winter just for busting brush in Arizona and South Texas, even when snakes are not a concern. They stay in place and feel like they were actually designed to be used for walking through rocky, brushy off-trail places.
