The Spark has been designed around an activity-specific anatomical last to match the ergonomic and biometric needs of fast hikers. The shoe fits like a glove around the foot, and its excellent forefoot and heel retention provides solid support for high performance in the most technical terrain. In addition, the comfortable and breathable ORTHOLITE® footbed keeps the foot cooler and drier.
The Pebax® foam plate of the Impulso technology sits in a balanced EVA midsole geometry, providing a lightweight, durable platform that supports the foot during intense fast hiking, keeping the shoe’s lateral stability when moving fast downhill or on uneven terrain. In addition, the V-Shaped ESS insert plate at the midfoot delivers torsional support and helps to prevent ankle injuries.
The midsole unit features Tecnica's exclusive Impulso technology that combines the benefits of a high-rebound EVA and a full-length Pebax® foam plate, delivering superior cushioning, explosive energy return and long-lasting elasticity. As a result, the Spark allows a comfortable and forgiving fast hiking experience on the most technical terrain.
