One week before leaving for my 4-day Havasu Falls hike, I finally decided my broken-in trail shoes weren't going to cut it. I ordered these, tried them on the day they arrived, and left for my trip. They were great! In sand, on rock, in mud (during down-pour)....I was always able to keep my footing. As for comfort, they are the most comfortable sneakers I've owned. I find most sneakers are too narrow for me. These lace across most of the foot rather than just the center which I loved. My feet felt great (No slipping ~ No blisters) on the steep grades we walked on, and even after the climb out of the Canyon. I highly recommend these!!
