These kicks engage your core, gams and glutes with every step and activate your entire back muscle chain at a greater amplitude, helping you reap even more rewards from your regular workout and achieve a better biomechanical balance. Ideal for everyday exercise from the treadmill to dance class (or just chasing the kids around the house). Includes DORSI 0 (neutral/barefoot level) and DORSI 2 (increased intensity) insoles. Whole and half sizes 6-11. Breathable mesh and high gloss synthetic leather upper with leaf-foil filigree pattern.
