I have had these shoes for four months now and they are still holding up well even after about few hundred miles of wear. I've worn them from general traveling to trail runs. I like the fit of the shoe. The shoe fits snug but not tight. The arch feels supported in this shoe. The toe box has good room for my toes and the heel feels locked. I am getting to like the non removable foot bed construction. It has a nice cushion. No insole edges to weary about rubbing the skin around the arch area. I purchased these shoes at a Merrell retail store; therefore, I was able to try them before purchasing them. The young gal working there was helpful in directing me to the right purchase. The shoes are comfortable without socks and I have never worn socks with them. That said, even with the built in treatment of "M-Select FRESH", over time the shoes will develop an odor; especially running in humid tropical regions. The shoe hand washes well with some Oxy-Clean spray on stain remover.
