BALANCED CUSHIONING™: Our Balanced Cushioning™ platform positions your heel and forefoot at an equal distance from the ground, encouraging better alignment and form.
VIBRAM® LiteBase: According to Vibram®, Vibram® Litebase outsole reduces 30% of the overall sole weight through a reduction of the sole thickness by 50%, while maintaining Vibram quality in grip, traction, and durability.
