I was worried about purchasing these shoes online because no store around me has them, so I was buying blind. they were to be used on a week long trek through the grand canyon in summer. They worked very well! Extremely comfortable, very durable, and wore well. The boots were completely waterproof, as I waded through a creek several times, and as long as the water didn't cover the top of the shoe, my foot stayed dry. the gore tex lining made the shoe slightly hotter, but I was wearing two pairs of moisture wicking hiking socks and my feet never sweated. The thick sole is cushioning, has incredible traction and didn't slip over large slippery boulders. It insulated my foot very well from the hot ground. They had great ankle support and resisted torsion very well whenever I stepped on an uneven rock. there were several times where I would've rolled my ankle if I had been wearing different shoes, but I ended up making it home without any injuries. They did seem to get a little larger than their size after being broken in for a week or so, but it wasn't much of a problem. buy with confidence if you're looking for an excelling heavy hiking boot for serious terrain!
