Song Sneaker Bounce or boost which is comfortable to walk
Song Sneaker Boost is more comfortable. Bounce is the shock absorption technology for Adi mid-to-low-end basketball shoes, while boost is the shock absorption technology for mid-to-high-end shoes. Song Sneaker Boost is to make TPU like popcorn, which is "exploded" into particles under high temperature and pressure, and then synthesized into the midsole part. In terms of cushioning and rebound, Boost is very good, and it is less affected by external temperature. It still has good performance in cold temperatures and has good durability.
Comparison of Song Sneaker bounce and boost
The difference in midsole material: Ultra Boost uses a Boost midsole. This is a type of E-TPU (Expanded-Thermoplastic polyurethanes). Boost is to make TPU like popcorn, "explosive" into individual particles under high temperature and pressure, and then synthesize the midsole part. In terms of cushioning and rebound, Boost is very good, and it is less affected by external temperature. It still has good performance in cold temperatures and has good durability. The alpha bounce midsole Bounce is a kind of EVA. Traditional running shoes simply cut a piece of EVA material and use it on the midsole, both in terms of performance and durability. Of course, EVA materials have also derived a variety of variants. Almost all sports brands have their own unique EVA, which is named with various technologies. They are usually mixed with other polymer materials, with different densities and weights, and are made into midsoles by injection molding and compression molding.
The difference in upper materials: Primeknit upper for Ultra Boost and Fused mesh upper for alpha bounce. This is another obvious difference besides the midsole. Ultra Boost is also equipped with Heel Counter heel protection structure and the common anti-rotation system Torsion System. Ultra Boost is not light in running shoes, but the alpha bounce is heavier, the same size is US 9, it weighs nearly 26g after measurement-depending on the avant-garde shape of alpha bounce, it may also be adidas that it is more hopeful that it is not pure sports A pair of shoes can also adapt to many life scenarios, so the weight is not so important.
