Kenetreks changed my whole perspective on what a comfortable and nimble boot can be. I used a lot of high end boots when mountaineering was my job and none of them have come close to the comfort of these boots. Despite the hype, I've put 4 hard seasons on them and they're still stand-in-water-proof, but the soles are about shot and will probably need a re-tread next year. But I guess thats the trade off for a quiet and grippy sole. My 2 cents
