What’s New in the Prime X3 Strung?

Upper: STRUNG Construction Continues

The Prime X3 retains its signature STRUNG upper, a precision-engineered woven material built for targeted support and breathability. There are no major upper changes noted in this update, so fans of the previous version will feel right at home. Expect the same secure wrap, lightweight feel, and adaptive comfort.

Underfoot Updates: Power and Propulsion

Three Layers of LIGHTSTRIKE PRO

The Prime X3 features a triple-layered LIGHTSTRIKE PRO midsole, creating a dynamic blend of cushioning, rebound, and energy return. The high stack height provides long-distance protection while maintaining a lively, efficient feel.

Carbon Plate + ENERGYRODS 2.0

A top carbon plate works together with carbon-infused ENERGYRODS 2.0 beneath, delivering a snappy, propulsive ride. This dual system helps guide the foot forward while keeping transitions smooth and stable.

LIGHTTRAXION + Continental Grip

The updated LIGHTTRAXION outsole reduces weight and thickness while improving efficiency. With strategically placed Continental rubber, the shoe maintains strong traction—especially during quick toe-off—giving runners secure footing at any pace.
