So far I have loved this shoe for trails and as a great looking casual shoe. The mid-top version is designed with an inner bootie and no tongue, which can make putting the shoe on a bit difficult if you have a wider or bigger foot. I wear a regular width size 12 normally and need a shoe-horn to get these on. That said, once they are on they are incredibly comfortable. Hiking on rocky mountain trails, I find the shoes grip and perform exactly as I would like. While the inner bootie design makes it tough to get on at first, it holds your foot in place very well while running or hiking. Wide-footed people may want to consider the other version of this shoe that looks like it has a standard shoe tongue.
