Thanks to the waterproof and breathable Gore-Tex® Extended Comfort membrane, your feet stay dry and comfortable in any weather. The upper is reinforced with a TPU film laminated to a polyamide mesh to protect high-wear areas such as the heel and toe cap and to increase the shoe’s durability.
The Vibram® Megagrip™ sole guarantees excellent traction on a wide variety of surfaces, whether dry or wet, while the EVA Exoshell Cage protects your feet and the midsole from sharp rocks.

Technologies and manufacturing processes

STABLE FOOT SUPPORT
The Pebax® foam plate of the Impulso technology sits in a balanced EVA midsole geometry, providing a lightweight, durable base that supports the foot during intense fast hiking and maintains the lateral stability of the shoe during fast downhill movements or on uneven terrain. Furthermore, the V-shaped ESS plate at the midfoot provides greater torsional stability and helps to prevent ankle injuries.
SPECIFIC FAST HIKING COMFORTABLE FIT
The Spark was developed around an activity-specific anatomical last to meet the ergonomic and biometric requirements of fast hikers. The shoe practically hugs the foot and the excellent support in the forefoot and heel area provides solid support for maximum performance on technical terrain. In addition, the comfortable and breathable Ortholite footbed keeps the foot cooler and drier.
REACTIVE CUSHIONING
The midsole area features Tecnica's exclusive Impulso technology, which combines the benefits of high-rebound EVA and a full-length Pebax foam plate for excellent cushioning, explosive energy return and long-lasting flexibility. In addition, the exclusive Flex Groove design of the outsole provides targeted flex points that increase flexibility and improve forward movement.
