Recently, more and more runners run on not only a jogging course but also a treadmill in a fitness club or their houses. Different footwear functions on treadmill running with overground running are required because of quite deferent running conditions. The purpose in this study is to clarify the basic elements to design the specific footwear for treadmill running. It is focused on that the difference of foot motion in the overground and the treadmill running. Reafoot evertion angle (β), tibial internal rotation angle (γ) and foot plantar pressure distribution were measured under the treadmill running and overground running. As a result of the motion analyses, it was confirmed that treadmill running produced the shorter step width, larger foot angle to the running direction, smaller maximal β(β_<max>,) and γ(γ_<max>), and smaller foot plantar force. As increasing running speed, β_<max> was also increasing and γ_<max> was decreasing. It was suggested that the treadmill running might reduced the risk of running injuries for not only over-pronators but also under-pronators.
