A Brief History into Running Shoe Performance and Biomechanical Research

Studies relating to running performance have been ongoing since the 1930’s.

James and Brubaker (1973) Clement and Taunton (1980)

The progression of running shoe design between 1852 and the modern day.

The contribution of Adolf Dassler in 1926 (Davis, 2014) The emergence of the first scientifically tested running shoe in 1962.

What are the important features of a running shoe in regards to injury prevention?

AdvantagesHeel Counter The heel counter has an important role in controlling excessive calcaneous

eversion during running motion (Nishiwaki and Nonogawa, 2015). The use of a rigid heel counter will aid the correction of overpronation and

will therefore reduce the risk of Achilles tendon injuries (Dubin, 2006). Midsole The midsole of the shoe provides cushioning to dampen the impact forces

placed upon the joints of the lower extremity (McPoll, 2000).Outsole The outsole of the shoe enhances the ductility of the material and

increases the energy-return effect of the material after the push-off phase when running (Chen et al, 2014).
