Adidas Adizero Adios Pro 4 Chalk White Carbon Racing Shoe

Understated Chalk White keeps the focus on what matters: an efficient carbon-assisted ride built to hold fast road pace for 21 or 42 kilometers.

Race-day purpose

Made for marathon and half marathon racing, personal-best attempts and the quickest sessions in a training cycle. It feels fast, responsive and propulsive, with neutral support.

• Lightstrike Pro: light cushioning with lively rebound.
• EnergyRods: carbon-infused rods for a smooth, efficient toe-off.
• Stripped-back upper: keeps the fit light and secure at speed.
• Continental Rubber outsole: confident grip on the road.

The neutral white finish pairs with any race kit, so it is easy to make this your go-to shoe for every goal event on the calendar, from spring half marathons to autumn marathons.

Fit & sizing

Secure, neutral racing fit in EU sizes 36 to 47.

Most performance running shoes are built on a single unisex last: the shoe is identical, only the size label changes. A US women's 8.5 is a US men's 7.

Use the unit switch above to move between US men's, US women's, EU and UK, or open the size guide for the full conversion chart.
