My son has had several pairs of Merrills. They fit well and wore well. If his foot would stop growing I could tell you how long they lasted.
I have a narrow foot and have a hard time finding a boot to fit. I have had good luck with Asolo. I replaced the insole with Superfeet. Unfortunately they turned into bathtubs on the trail at Philmont and in the drying process, the sole under the toe charred and came apart. Now I am in the market for new boots myself. I don't think the soles on those boots can be replaced. I don't remember the model.
