Let me start by saying that I much prefer hiking in trail runners than any type of boot. These are a bit heavy for my taste but they are far more flexible and responsive than hiking in my winter boots. We had recently moved and the trail conditions near home are far more a combination of wet & muddy trail than deep snow. Without that deep snow, I'm wanting to hike longer days, more miles. My trail runners are not waterproof and my winter Merrell boots are far too heavy and stiff. After some debate, I opted for these. I had them out on the AT where the trail had turned into a stream, well a muddy stream. It had snowed a few inches the day before and was then a mushy mess. Despite stomping through deep puddles and mud, my feet were 100% dry. They were comfortable on trail, but I found them not to be that comfortable on a long stretch of road walking. The grip was fantastic as I cruised over wet rocks and trail during a hours long hike through freezing rain and sleet. I'm planning on getting the trail runner version of these since they were very comfy on my feet and provided good support on trail and the TR version is built nearly identical to these but much lighter (and not goretex.
As for the boots, I'll truthfully only use these when trail conditions won't permit a non-waterproof shoe. That's not to say these aren't good and if you like a boot, you'll love these, but boots just aren't for me.
