Adizero Pime X Evo

Originally engineered to obliterate the world’s fastest 100K road time, the adidas adizero Prime X Evo now arrives as a rare opportunity to experience prototype-level innovation firsthand. This concept racing shoe represents the outer edge of what’s possible in long-distance road performance—built not only for record-chasing ultramarathoners and marathoners, but also for runners who want to own a true piece of modern racing history.

At its core sits the tallest stack of uncompressed Lightstrike Pro Evo superfoam ever created, delivering extraordinary energy return with a formulation that’s an astonishing 35% lower density than the foam used in the Adios Pro Evo. The result is a ride that feels impossibly soft, ultralight, and endlessly propulsive. High midsole sidewalls cradle the heel in a bucket-seat geometry, creating inherent stability despite the towering stack.

Debuting alongside the foam is the Energy Rim, adidas’ latest evolution of its championship-tested propulsion system. Working in harmony with an aggressively sculpted toe rocker, the Energy Rim enhances stiffness, efficiency, and forward momentum—making it easier to sustain fast paces deep into ultra-long efforts. Every stride feels guided, lifted, and relentlessly efficient.

Up top, a newly patterned featherweight mesh upper disappears on foot while maintaining precise race-day support. Beneath, the outsole sees a major traction upgrade: full-length Lighttraxion rubber paired with Continental rubber in the forefoot delivers confident grip on slick roads without sacrificing weight. Unapologetically bold and uncompromising in execution, the Prime X Evo stands as the pinnacle of road racing experimentation.

MIDSOLE

• Lightstrike Pro Evo superfoam is the lightest uncompressed TPEE that adidas has produced. It's 35% less dense than the Adios Pro Evo version for maximum deformation and energy return at an incredibly low weight.
• Aggressive forefoot rocker acts as a fulcrum situated at 60% of the overall shoe length, mirroring the Adios Pro Evo for maximum forward-rolling efficiency.
• Energy Rim is a next-generation stiffening element, evolved from Energy Rods. It forms a horseshoe-style perimeter to preserve underfoot softness with custom-tuned propulsion.

OUTSOLE

• Lighttraxion GCPU compound is full-length cast polyurethane, offering strong grip and flexible durability at a reduced weight.
• Continental™ rubber is a staple in adidas performance shoes to provide extra traction in the forefoot for variable road conditions.

UPPER

• Ultralight engineered mesh secures your foot with breathable material and the minimum support for powerful racing.
