Lightstrike Pro Foam: Premium Cushioning

Borrowed from road marathon models (Adios Pro), Lightstrike Pro foam offers an exceptional weight-to-rebound ratio. It absorbs impact over time while relaunching the stride.

In this version 2, it feels slightly reworked to provide a softer feel while remaining ultra-responsive.

Energy Rods System

Instead of a traditional plate, adidas uses Energy Rods that follow the metatarsals. They provide the stiffness needed for propulsion while allowing for lateral adaptability on uneven ground.

Coupled with the pronounced "Rocker" profile, they create a rocking effect that saves the runner's energy as the miles add up.

Continental Sole & Mesh Upper

The Continental™ rubber outsole is an absolute benchmark, ensuring reliable grip on both dry and wet rock. The lugs have been optimized for more versatility.

The seamless technical mesh upper is designed to be more abrasion-resistant than v1, while ensuring precise midfoot lockdown essential for descents.

Agravic Speed Ultra 2: For Which Type of Runner?

What Size to Choose for the Agravic Speed Ultra 2?

The Adidas Terrex Agravic Speed Ultra 2 generally fits True to size. The fit is precise at the midfoot to ensure support, but the "Toe Box" offers enough volume for long distances.

Our advice: Take your usual running shoe size. If you are between sizes, go for the half-size up to account for foot swelling during ultras.

Note on fit: The upper has been revised compared to v1 to provide better heel lockdown and prevent friction.

Yes, it is one of the best trail shoes for paved sections. Thanks to the Lightstrike Pro foam and its road-inspired geometry, it is very comfortable and efficient on asphalt, which is perfect for transition trails.

Lightstrike Pro is a resilient foam. Unlike some very fragile PEBA foams, it retains its rebound properties for a long time. The Continental sole protects the bottom of the shoe well, ensuring very decent durability for a competition shoe.
