The Precision is a marathon shoe of choice for many club runners and it is easy to see why. While being notably lighter than a regular training the midsole depth and feel is not radically different Ð it is a bit less cushioning and more flexible but the depth is there and it does not give a huge shock to the system. It is not a support shoe but is quite stable and so even mild over-pronators might be happy in it for 26.2M on a one-off. It is also very good for faster training.
