Refining the legendary runner, the adidas Ultraboost 20 uses precision design to remove anything not needed to deliver the most enjoyable of runs. The new Primeknit upper utilises Tailored Fibre Placement (TFP) technology alongside a new midfoot cage to deliver a more stable and secure fit. The TPU heel cage returns but is placed on padded neoprene at the back to deliver better comfort and performance on the track. Finished with the signature Boost midsole and Continental Stretchweb outsole it delivers the same fun, energising run.
