Adizero Prime X3 Strung

The Adidas Adizero Prime X3 Strung redefines the super-trainer category with a blend of cutting-edge innovation, cushioning, and precision design. Built as the ultimate fusion of training comfort and racing technology, this over-stacked powerhouse delivers the exhilarating feel of a marathon racer in a package durable enough for daily performance.

At its core lies a triple-layer Lightstrike Pro midsole — a plush, high-energy system engineered for maximum rebound and impact protection. Replacing the previous dual-plate setup, Adidas integrates carbon-infused Energy Rods beneath the top plate for a smoother, more efficient stride. The result is a propulsive, trampoline-like sensation that keeps your legs fresher over long sessions while amplifying speed and momentum.

The upper showcases Adidas’ groundbreaking Strung technology, a precision-woven textile created through data-driven mapping to deliver targeted flexibility and support. The forefoot expands naturally for unrestricted toe splay, while the midfoot and heel are reinforced to keep you secure atop the towering stack of foam.

Underfoot, the redesigned Lighttraxion outsole enhances durability and trims weight compared to its predecessor, providing confident grip on a variety of surfaces without compromising efficiency.

Every element of the Prime X3 Strung has been crafted for performance and indulgence alike. Whether you’re logging long runs, recovering between races, or chasing marathon-level comfort in everyday training, this shoe transforms every stride into a smooth, exhilarating experience.

MIDSOLE

• Lightstrike Pro superfoam forms three layers of improved supercritical TPEE that's lighter, softer, and bouncier than before.
• Full-length carbon fiber plate is top-loaded for stability, foam loading, and rigid snappiness.
• Energy Rods 2.0 are made of carbon fiber-infused polymer and scoop-shaped to match the revised rocker point for optimal running economy.

OUTSOLE

• Lighttraxion GCPU compound is cast polyurethane, offering strong grip and flexible durability at a reduced weight.
• Continental rubber section under the medial forefoot provides sticky and durable traction in the important toe-off area.

UPPER

• Strung material is created by placing each thread into a single composite with specific zones and properties, resulting in a cohesive upper tuned for support and flexibility where needed. This version adds flexibility in forefoot expansion zones.
