Adidas Adizero Prime X 2 Strung

“" Adizero Evo Prime X – Tailored individually to each runner, the Adizero Evo Prime X has been precision-engineered for one purpose: speed. Every element – from the ultra-responsive midsole to the precision-fit upper – is designed to help maximise running economy and unlock personal bests. Born from relentless testing, feedback and refinement between athletes and product experts, each pair was tailored to its runner. The stack height is calibrated to the forces each athlete generates, providing optimal responsive cushioning, while the stiffening structure is composed of materials tuned to individual biomechanics. Ultracharge – An innovation many years in the making, the athletes’ race day shoes benefitted from adidas’ brand new Ultracharge technology. Entering the high-pressure vessel five days prior to the race, air bubbles are pumped into the empty gaps of the shoes’ midsole foam. As the pressure increases there is an improvement in the energy return of the shoes. CLIMACOOL Pre-Cooling & Per-Cooling System – Before the race, athletes used a combination of cooling and insulating technology to enhance thermal regulation. Combining a cooling vest and a CLIMACOOL insulating fan jacket – as worn by the AMG Formula 1 team – this minimized athletes’ core temperature and heart rate in the first hour of performance, supporting overall endurance. During the race, each athlete had their own set of cooling necks, swapped out and refreshed. Created by adidas specifically for this attempt, the cooling neck is ergonomically moulded to the main arteries and veins for maximum cooling. Clima 3D singlet – The Clima 3D singlet features a newly developed CLIMACOOL 3D embossed material technology, body-mapped to areas with the highest skin contact and sweat production for improved airflow, accelerated sweat evaporation and enhanced cooling. The new CLIMACOOL 3D technology will be available in 2026. TechFit short tight – Complementing the Clima 3D singlet, the TechFit short tights feature stiffening bands strategically placed for each athlete’s body composition which stabilizes the hips to support running economy and endurance performance under fatigue. The new TechFit technology will be available in 2026.”
