Adizero Prime X 3 Strung

$300.00Super Trainer

The Adidas Adizero Prime X3 Strung is a maximalist, rule-breaking running shoe boasting a 50mm stack of Lightstrike Pro foam, a carbon plate, and Energy Rods 2.0, designed for a unique and exhilarating ride. While some runners experience a fun, propulsive springboard effect, especially at faster paces, others find it initially firm, heavy, and less bouncy than desired, often requiring a break-in period. Praised for its excellent durability and improved stability over its predecessors, it is recommended as a supertrainer for long-distance speed work and marathon training, though its very high price and polarizing ride make it a specialized option for enthusiasts rather than an everyday choice.

Highlights

Propulsive, springy ride with noticeable pop and energy return, particularly at faster paces.
Highly durable Continental rubber outsole providing excellent grip and longevity.
Improved stability over previous versions, aided by a wide base and dual carbon stiffening elements.
True-to-size fit with ample toe room and generally secure, breathable upper.
Well-suited for long runs and marathon training, offering cushioning and speed assistance.

Considerations

Firm and dense initial ride that often requires break-in miles to soften.
Feels heavy and bulky underfoot despite weight reductions from prior iterations.
Upper can be stiff, making lockdown adjustments difficult and occasionally causing heel lift.
Can feel unstable or wobbly at slower paces or for heel strikers.
Less ideal for race day due to weight, firmness, and stack height limitations.
