I am breaking in my next pair of running shoes. My Brooks Cascadia 7's are just about out of tread. They were a great shoe, but a little stiff in areas. These Montrail Fluidflex have the idea weight and cushion I'm looking for. I'm not thrilled about them being dark in color which can lead to hot feet in the summer. The Fluidflex have a super light mesh that breaths well and makes me think that heat might not be a issue. The only downside I've noticed with the Montrails are that they grab high on my ankle. I'm hoping that part softens up with use.
