The upper seems well made and fits my foot well (see my other Xero review if you would like a more detailed description of my foot shape for reference, but in general it is high arched and with a high instep, medium width), but the sole is MUCH stiffer than I was expecting and for me they are not wearable. If you are looking for a hiking boot that is relatively flexible by hiking boot standards, this may work great for you. I was expecting these to be made with something much closer to the flexibility I am accustomed to from the other Xeros I own and love. For me, a high degree of flexibility and ground feel is paramount, and that is why these have to go back.
