Weight was always the UltraBoost's weakness. The material that made it comfortable is dense, and a decade of versions carried the penalty; reviewers consistently rated it a comfortable shoe rather than a fast one.
Light Boost was the answer: a reformulation of the same expanded pellets that removes roughly thirty percent of the mass while, adidas claimed, adding a few percent of energy return. The UltraBoost Light launched with it in early 2023, ten years after the first Boost midsole reached the market.
The rest of the shoe was reworked to match, with a Primeknit+ upper and a revised Linear Energy Point unit under the arch, and the result weighed close to three ounces less than the original UltraBoost. Reviewers treated it as the first version of the shoe that could genuinely be run in rather than simply worn.
