When running at 12 km/h, the values of "negative work of ankle plantarflexion torque" were compared between products equipped with the Smooth Speed Assist function in midfoot and forefoot running styles and products without it (in-house). It was confirmed that the value was reduced in the equipped products. (※Individual results and sensations may vary.)
