These pedals provide a larger non-slip platform to set your feet upon when using the MagneTrainer as a leg exerciser. They also have easy-to-adjust Velcro pedal straps that fit all foot sizes. The pedal straps are soft and wide to maximize comfort and support. Important! If you plan to switch back and forth between these pedals and the standard pedals, we highly recommend that you purchase the MagneTrainer Quick-Connects. This will prevent damage to the pedal arms that can occur from frequently changing pedals.
