Love this boot! I took it hiking through White Sands National Monument, up Guadalupe Peak in Texas, into caves, and all around Big Bend National Park. The farthest I hiked in one day in these shoes is 15 miles, so I can't speak for anything more than that. They are relatively lightweight for a hiking boot, yet stylish (important to me) and sturdy. They were true to size and held up well through it all. They are not as high as some hikers like their boots for shoe tieing purposes but I think this was the perfect length to give me ankle support. My friend also hiked in similar Timberlands, but mine were thicker and more supportive. Would highly recommend to beginner hikers!
