Maybe the improvements in the weight of the shoe matter, not just the spikes. Reducing the weight is more than a matter of shaping the shoe - I think most improvements now come from using new materials. The weight is added at an extremity and has to be lifted every time you pull your foot up. I know this makes a noticeable difference for long distances, but I'm not sure about sprints, where you take a much smaller number of much more powerful steps. |
