The shoe offers a very impressive balance of deep cushioning and low weight. Nike says React: is 30 per cent lighter than adidas Ultra Boost foam and the PU that Brooks uses in many of its shoes it lasts 20 per cent longer than comparable midsole compounds, so runners can expect to get 600 instead of 500 miles out of their shoes before replacing and it gives 13 per cent more energy return than the current Nike Lunar foam (ie, how quickly the foam returns to shape after compression and helps push your foot off the floor). React is lightweight, resilient, soft, durable, cushioned and responsive all at once.’ And why they can normally be lightweight or durable.
That’s why foam can usually only provide cushioning or energy return. On the flipside, hard materials give the most energy return. Normally, materials are soft because they absorb energy. React is a rubber-based compound that has been developed by Nike the company says it will make for greater consistency in the manufacturing process.īret Schoolmeester, Senior Director Global Running Footwear, says: ‘React is revolutionary in that foam can be lightweight or resilient but usually it can’t be both of these things and also be durable.
Midsole materials used by shoe brands usually have two things in common: they are made from a form of foam compound (EVA, PE, PU), and they are non-proprietary materials invented by chemical companies then licenced to brands and tweaked to their specifications.
It’s all about the midsole cushioning, which Nike calls React. Nike claims the shoe is a game-changing innovation.
