adidas Adizero Prime X 3 Strung - Unisex Racing Shoes

Push the boundaries of your training with the adidas adizero Prime X 3 Strung, a high-mileage super trainer built for explosive comfort and joyful performance. This over-stacked running shoe blends next-gen propulsion, plush cushioning, and responsive bounce—making it ideal for long runs, daily training, and recovery miles with a racing feel.

As the original over-stack super shoe, the Prime X 3 returns fully reinvented. It layers three levels of adidas Lightstrike Pro superfoam, combines a full-length carbon plate with new Energy Rods 2.0, and wraps your foot in a precision-engineered Strung upper. While not legal for World Athletics–sanctioned marathon races due to its stack height, it’s a game-changer for training and non-elite racing—providing maximum protection and forward propulsion.

The Strung upper adapts to your stride with zoned flexibility and secure hold, while the updated Lighttraxion outsole offers lightweight grip that lasts. Whether you're logging serious weekly miles or looking for leg-saving comfort on long runs, the Prime X 3 delivers a trampoline-like ride you won’t want to take off.

MIDSOLE

• Lightstrike Pro superfoam in three stacked layers offers elite-level energy return, with enhanced softness and rebound for long-lasting comfort.

• Full-length carbon fiber plate is top-loaded near the foot for maximum snap, stability, and efficient foam compression.

• Energy Rods 2.0, made of carbon-infused polymer, are scoop-shaped to follow your stride path and enhance propulsion while improving running economy.

OUTSOLE

• Lighttraxion GCPU outsole uses cast polyurethane for durable grip with less weight, ensuring traction without slowing you down.

• Continental rubber in the medial forefoot zone gives added grip and durability at toe-off for confident push-off.

UPPER

• Strung upper is precision-engineered with individually placed threads for targeted support in the midfoot and heel, plus stretch zones in the forefoot for natural movement.

• Forefoot expansion zones increase comfort by allowing flexible toe splay while maintaining lockdown and structure.

Note: The adidas adizero Prime X 3 exceeds the legal stack height (40mm) allowed for World Athletics–approved marathon racing. Ideal for training and non-regulated races.
