The lightest shoe in the group, the Nike Free Trainer is designed to provide natural, weightless, barefoot-like feel. Flywire cables extend down from the laces to provide better fit. The mesh upper doesn't have any stitching on its body and is very well ventilated. It has rubber pods in high-wear areas and provided good lateral support and excellent comfort and flexibility, but the sole pattern is not as well suited for tougher terrain. This would be a nice choice to stash away as a get-home shoe for urban office dwellers.
