Guide
Full breakdown
The Adidas Ultraboost debuted in February 2015 and was called 'the greatest running shoe ever' by Kanye West shortly after, igniting a massive crossover into fashion and streetwear. It features a full-length Boost midsole (TPU pellets), a Primeknit sock-like upper, and a Continental rubber outsole. The Ultraboost pioneered the premium running-shoe-as-lifestyle trend and has been through numerous iterations while maintaining its core Boost cushioning identity.
Questions answered
FAQ
Is the Ultraboost still worth buying?
For pure comfort, absolutely. The Boost cushioning remains excellent. What has faded is the fashion cachet and exclusivity. As a running or daily comfort shoe, it is still one of the best options, especially at discounted prices.
Is the Ultraboost good for running?
Yes, it handles daily training well with excellent energy return and cushioning. Not a racing shoe, but a very capable daily trainer. Many runners still prefer Boost over newer foam technologies.
Does the Ultraboost run true to size?
The Primeknit upper runs slightly snug. Half a size up from your normal Adidas size is the most common advice. The knit does stretch slightly with wear.
Why did the Ultraboost decline in popularity?
Market saturation, constant new colorways, and the natural hype cycle moved attention to other shoes. The Ultraboost became too common to maintain its premium image. The shoe itself has not gotten worse, just less exclusive.
Does Boost cushioning last?
Boost midsoles hold their cushioning properties well over time compared to EVA foams. The trade-off is that the white Boost material yellows and stains. Cushioning performance remains strong for 500+ miles of running.
