The Boost 2 features a greater energy return.
The Adidas Energy Boost 2 Running Shoes feature an updated midsole unit which will feel different to anything you've ever worn before. The unit created in conjunction with BASF, is constructed of small polyurethane capsules which are fused together with high pressure steam. The result is a platform which is much more responsive than traditional EVA, absorbing the energy in the footstrike and translating it into reactionary power when you lift off. (See the videos tab for a side by side comparison with EVA material.) The Boost midsole unit is also 30% more temperature resistant than EVA, allowing it to retain its composite structure better, improve performance in varying conditions and enhances durability. Other new technological advances that Adidas have made include incorporating TechFit technology into their running shoe uppers. TechFit is a lightweight but strong material which in this shoe helps to support the foot by being supremely flexible and is mesh lined for optimal breathability. Welded overlays also help to enhance the fit of the shoe as well as keep the seamless upper as lightweight as possible.
