Adidas Adizero Prime X 3 Strung

Who Are Adidas Adizero Prime X 3 Strung For?

This is a shoe for experienced runners who want to blend hard workouts and long efforts into one maximalist "super trainer." Because its stack sits above World Athletics' legal racing limit, it's aimed at training and fast long runs rather than official race-day PBs. If you want a lightweight, low-slung racer or a plush slow-recovery cruiser, look elsewhere — this rewards runners who push the pace.

Feelings and Experience

Underfoot the Lightstrike Pro foam feels soft yet lively, with a deep, cushioned landing that springs forward thanks to the carbon plate and Energy Rods. The tall platform creates an aggressive rocker that wants to roll you into faster paces, so it comes alive when you lean in and open up. Its honest quirk: at that towering stack, the ride can feel a touch tippy and wobbly at slow, easy speeds.

Performance Specs

• Drop: 13mm heel-to-toe offset — the tall heel-to-toe gap eases the heel strike and suits long-effort comfort

• Cushioning: Maximum — Lightstrike Pro PEBA superfoam for deep, protective softness

• Responsiveness: High — full-length carbon plate plus Energy Rods 2.0 drive a strong, propulsive rebound

• Stability: Medium — neutral platform with a trainer-width base, though the high stack adds some wobble

• Pace: Optimal for 4:15–5:00 min/km (6:50–8:00 min/mile) — uptempo training, not all-out sprinting

Best Distances and Maximum Speed

It excels over the half marathon and marathon, with fast long runs and tempo workouts as its true sweet spot. Push it toward 4:15 min/km (roughly 6:50 min/mile) and the rocker and plate work at their best. It's happiest holding a strong, sustained pace rather than short sharp intervals.

Technologies and Materials

The midsole stacks Lightstrike Pro superfoam over a full-length carbon plate paired with Energy Rods 2.0, wrapped in adidas's robotically-threaded STRUNG upper. RunRepeat's calipers measured 48 mm heel / 35 mm forefoot for a 13 mm drop, with a weight of about 291 g in a men's US 9 — noticeably heavier than a true racer, the trade-off for all that foam.
