Have worn these across three days of field work totaling approximately 30 hours of work and my feet are holding up great. I was worried upon first trying them out because they upper (the part of the shoes just above where your toes connect to the rest of your foot) seemed pretty low. I felt the top of my foot touching it and was concerned that it would cause blisters over the coarse of an entire work day. Thankfully the leather material stretched within a days work and fit my foot more comfortably. Even with my incredibly flat feet, these boots held up great. Very happy with this purchase
