Adidas Adizero Prime X 2.0 Strung

Who Are Adidas Adizero Prime X 2.0 Strung For?

This is a max-stack "super-trainer" for experienced runners chasing fast long runs, marathon-pace sessions, and tempo efforts, not a do-everything daily trainer or a gentle recovery shoe. Because it sits above World Athletics' legal stack limit, it's aimed at training and personal-best pushes rather than official racing. If you want a light, nimble 5K flyer, look elsewhere in the Adizero line.

Feelings and Experience

Underfoot it feels enormous and springy — the tall Lightstrike Pro foam is soft yet lively, and the carbon rods snap you into the next stride with a strong forward tumble. That height comes with a catch: at easy jogging paces it can feel a touch tippy and disconnected from the ground, but as you lift the pace it settles and rolls with real momentum. It rewards a runner who keeps the tempo honest.

Performance Specs

• Drop: mid-range heel-to-toe offset — the height difference between heel and toe, tuned here for a smooth rolling transition

• Cushioning: maximum, Lightstrike Pro foam — plush, deep protection for long time on feet

• Responsiveness: very high — carbon EnergyRods plus the resilient foam drive a strong rebound

• Stability: moderate, neutral — a wide platform keeps the tall stack more planted than a narrow racer, though it stays slightly tippy slow

• Pace: Optimal for 3:45–4:30 min/km (6:00–7:15 min/mile)

Best Distances and Maximum Speed

It genuinely excels at the half marathon and marathon, with the sweet spot being fast, cushioned long runs and marathon-pace work. Push it and the technology peaks around 3:30–3:45 min/km (5:38–6:02 min/mile); below that pace the mass and stack blunt its edge.

Technologies and Materials

The midsole is a very tall stack (roughly 50mm) of Lightstrike Pro foam with multiple carbon-infused EnergyRods providing propulsion and structure. The Strung upper uses precisely placed threads for a light, adaptive lockdown. It's a heavier shoe than a pure racer, so treat that weight as the price of all this cushioning.
