I climbed my first 14er last weekend with these boots and I love them. I did not take the time to break them in, but I had no pain or blisters after a solid 4 hour hike up and down the incredibly rocky terrain of Mt. Democrat. They seem to be very solidly constructed and I appreciate that they are NOT made of leather. I ordered my usual athletic shoe size and the fit feels normal. For vegans/pseudo-vegans, this is as good as it gets!
