Nathan and Matt dig into the mailbag after sharing early thoughts on the New Balance SC Rebel and SC Elite v6 in this week's In For Testing. They cover a wide range of your questions, including whether unworn shoes age in storage, what makes a good all-terrain "safe" shoe, the biomechanical differences between forefoot rockers and toe-spring, and whether it's worth rotating flexible shoes with stiffer, rockered ones, and much more.
