These shoes are beautiful. I used them to go hiking around Colorado for the summer and there is no problem with my feet getting too hot in the hot summer heat. As other reviewers have mentioned, I get heel blisters when I hike in these boots for too long. My heel starts to hurt after an hour or two and I can feel a blister forming even after wearing special hiking socks. I solved it by putting large bandaids around my heels, but I need to find a true solution to this and I'll give it 5 stars. Since I am flat footed, my feet hurt after hiking in these for a while as well. There isn't much arch support, so I have to put in shoe inserts. The lacing is spectacular. Probably one of the best lacing systems in a hiking boot I have used. And very good ankle support and traction.
