With each new update, we raise the bar. Now you get the cushioning you didn't know you needed with the energy return you've always wanted. This version features 6% more Boost capsules and a supportive adidas Primeknit+ upper. It gives you an extra push of energy in each step that comes from the Linear Energy Push system, which offers forefoot and midfoot support.
