adidas ADIZERO ADIOS PRO 4 Product Description Brand new, unused Color: Core Black Size: 25.5 The Adizero Adios Pro series is the pinnacle of adidas' racing shoes, chosen by runners at the top of the world. The Adios Pro 4 is designed for runners who want to run faster, featuring functions that enhance running efficiency. It features ENERGYRODS 2.0, made with carbon, which enables smooth weight transfer from heel to toe and promotes a springy, efficient stride. A new rocker point in the midsole improves running economy. And the industry-leading lightweight two-layer LIGHTSTRIKE PRO provides cushioning even at fast strides, assisting in maintaining energy over long distances. The outsole combines Continental rubber, which is non-slip at the time of kicking off, and LIGHTTRAXION, which reduces weight without sacrificing grip. This product uses more than 20% recycled materials. Reusing materials from products that have already been made helps to reduce waste, dependence on limited resources, and the footprint of adidas products. Upper: Synthetic fiber Outsole: Rubber sole
