Co-developed by Answer4 and rig, this minimal running sandal strips away excess to deliver a purpose-built platform for runners. The midsole uses rig's proprietary EVA foam compound, tuned for compression-rebound balance that provides shock absorption and propulsion despite its low-profile construction. The outsole combines rig's original rubber compound with custom lug geometry for durability and traction across asphalt and uneven trail surfaces alike. A strategically positioned strap system locks the foot securely in place without creating pressure points, achieving a supportive fit through minimal structure.
