There's a lot more to running long distances than just getting from here to there. It's about the breeze at your back, the rhythm of your stride, the freedom of the road. The adidas Adistar 2 are precision engineered for perpetual motion, ensuring that each step seamlessly transitions to the next, mile after mile. The dual-density midsole combines lightweight foam for resilient cushioning with a firmer compound that cradles the heel. An internal cage locks the foot in place for optimal support that never falters.
