Have gone on a few 5 to 8 km hikes, my feet give them a 5. As others have stated the tongue is too short, I do not understand why such a well built shoe would have such an oversight. I hike on trails through the woods, dirt, mud, some sand and gravel, no sharp rocks. For these conditions the boots excel, I am in central Canada where -25 to -30 is common, If the soles turn into bricks i will be disappointed, time will tell. So far i am enjoying the cushioned ride they supply, so much I have also purchased the Anacapa breeze, and the trail code GTX. Also i find they run hot, I will be using them in the winter and or in cool wet conditions.
