Soccer shoes showing non-elliptic outsole constructions achieve better stability properties especially with regard to stability referring to shoe-to-ground interaction. A tight, well shaped forefoot upper of the soccer shoe that prevents the foot from foot gliding inside the shoe was identified as a crucial factor for stability perception of soccer players. Thus higher medial and lateral forefoot peak pressures and pressure rates during soccer specific movements are evoked. Higher maximum supination excursion and higher supination velocities as well as higher ratios of shear force/vertical force indicate a more dynamic performance of the cutting movement in shoes that are perceived to have better stability properties.
