Running shoes Adidas ADIZERO ADIOS 4

The Adidas Adizero Adios 4 is a road racing shoe designed for neutral runners tackling distances from 5K to marathon. Built for fast-paced racing, it delivers a traditional race-day feel with enough cushioning to keep legs fresh over long distances.

The midsole uses Boost foam technology, providing a snappy and responsive ride with strong energy return. The forefoot offers good flexibility and smooth toe-off, while the thicker Boost heel adds protection and bounce suited to longer race distances. The Adizero Adios 4 feels lighter and more race-oriented than typical lightweight trainers, with a ride that works well for runners seeking both speed and durability across training cycles.

The upper fits true to size with a somewhat wider toe box around the outer toes while maintaining an overall snug racing fit. The midfoot features effective lacing that secures the foot without pressure points, and the heel counter includes slightly more padding than earlier versions for improved comfort. The narrow midfoot construction reduces overall lateral stability, though a torsion system extending into the medial midsole of the heel provides some rearfoot support for neutral runners.

The outsole combines Adiwear and Continental Rubber compounds for grip and durability on road surfaces, with extra carbon rubber reinforcement at the heel for high-wear areas. The Adidas Adizero Adios 4 delivers reliable traction in varied road conditions while maintaining the low weight expected of a racing shoe.
