Description
Optimized Boost features 20% more Boost in the midsole compared to the first-generation adidas Ultra Boost, this updated technology brings even more energy return. Torsion Spring is a lightweight construction for enhanced support on landing and a snappy transition to propel runners forward. The Primeknit 360 feels like a second skin, combining pure comfort with lightweight performance. Last but not least is the updated 3D heel frame – a stripped-back design cradles the heel, bringing the perfect mix of adaptability and support.
