A new day. A new run. Make it your best. These high-performance shoes feature a foot-hugging knit upper. Stitched-in reinforcement is precisely placed to give you support in the places you need it most. The soft elastane heel delivers a more comfortable fit. Responsive cushioning returns energy to your stride with every footstrike for that I-could-run-forever feeling

PrimeKnit+ Upper

A Primeknit+ upper encases each foot in breathable comfort. Feeling like a second skin, its seamless construction surrounds the foot in a fused yarn that combines pure comfort with lightweight performance

Boost Midsole

Boost is constructed from tiny TPU capsules that are moulded together to form a platform that is different to standard, solid foams; absorbing energy and then expelling it back out for a bounce-like effect

StretchWeb outsole

Manufactured from Continental rubber, the StretchWeb outsole completes the Ultra Boost 20 for a smooth transition through the gait cycle. Its web-like structure allows the shoe to stretch, for a flexible underfoot feel
