adidas Adizero Prime X3 Strung Men's Running Shoe

The Fastest Shoe adidas Has Ever Made

The adidas Adizero Prime X3 Strung is not a shoe for the faint-hearted. It's a boundary-pushing, record-chasing, engineering-first statement from adidas that asks one question: how fast can a shoe actually be? The answer is built into every layer of this radical silhouette — from the revolutionary Strung upper to the triple-stacked Lightstrike Pro midsole.

Strung Technology: A New Kind of Upper

The Prime X3 Strung features adidas's groundbreaking Strung upper — a textile innovation where individual threads are precisely placed by a robotic system to create a structure that's uniquely tuned for speed. The result is an upper that's lighter, more adaptive, and more aerodynamic than anything woven or knitted. It wraps the foot like a second skin and moves with you, not against you.

What Makes It Extraordinary

• ✦ Strung upper — robotically engineered thread placement for unmatched fit and weight savings
• ✦ Triple-stacked Lightstrike Pro midsole — maximum energy return with every stride
• ✦ EnergyRods 2.0 — carbon-infused propulsion system for explosive toe-off
• ✦ Continental™ Rubber outsole — race-proven grip on any surface
• ✦ Ultra-low weight construction — engineered to remove every unnecessary gram

For Those Who Run at the Edge

The Adizero Prime X3 Strung is adidas's most ambitious racing shoe to date — a shoe that exists to push the limits of what's possible. If you're chasing times that don't yet exist, this is where you start.
