Adidas Adizero Prime X3 Strung Black Grey Green Super Trainer

Cold, wet, gritty roads are where this colorway earns its keep. The dark Strung upper hides winter grime far better than lighter versions, while green accents along the midsole stop it from looking plain on bright days.

A max-cushion trainer, not a racer

Think of the Prime X3 Strung as a super trainer for steady road mileage. Its deep cushioning keeps the legs fresh, and its internal structure keeps the platform stable at a consistent pace.

• Deep Lightstrike Pro midsole: heavy, protective cushioning.
• Energyrods through the length: add structure so the ride stays controlled.
• Continental rubber: placed in the high-wear zones for a long winter of miles.
• Strung upper: dark Black and Grey with Green detailing.

Fit & sizing

True to size for most runners. Go half a size up if you want extra toe room on long runs. Brand new in the original box, 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.
