While this technology is great in theory, there have been some issues with overall volume in the toe box of Adidas’ shoes using Primeknit, primarily the Ultra Boost. This is Adidas’ version of Nike’s Flyknit technology (sorry Adidas, Nike got there first) and there truly are very few differences in the fit, feel, and function of this upper technology.Īdidas’ promo materials state that “ Primeknit is carefully engineered to naturally expand with your foot while you run to give you a more comfortable fit and help reduce irritation”. While the price may seem steeper than competing brands, the durability and resilience of this technology is worth every penny.

If you’re a regular runner and you haven’t tried out Boost cushioning I high recommend you do so. In my own experience, I’ve been able to wear a single pair of Adizero Tempos for eight hundred miles and a Supernova Sequence for over one thousand miles due the properties of Boost foam. It works great in small amounts for firmer, faster feeling shoes, and the cushioning stays largely uncompressed throughout the life of the shoe. This technology led to a sea change in the way that running shoe companies conceptualized the capabilities of foam EVA, and directly led to the massive advances in EVA cushioning we see today.īoost midsole cushioning is both soft and responsive, protective yet resilient, and highly durable. This TPU based technology made up of thousands of small foam pellets was first developed by a German chemical corporation.
