The cushioning system demonstrates a lower rate of fatigue decay compared to standard ethyl vinyl acetate foams, running shoes on jeans.
Since boost technology was introduced in 2013 it's been fitted into all existing styles of adidas shoes, but the adidas Ultra Boost Women's Running Shoe was the first to be completely built around boost. With no EVA, the midsole is entirely constructed from boost, giving you the ultimate energy return. The outsole has been re-designed with stretch web to work and compliment this by allowing boost to move and adapt, expanding with the foot and with no restrictions. If this wasn't enough, the heel counter has been made softer and opened up slightly around the achilles for a more natural feel and movement, but without compromising on its support. Moving upwards the upper is constucted from Primeknit, a single yarn, for a sock-like fit that, like the outsole, allows for the natural expansion of your foot but is still supportive with a slight compression. adidas boldly claim that this is the greatest running shoe ever, why not see for yourself?Features
