Starting its life at the Boston Marathon and now in its 9th iteration, the adidas Adizero Boston 9 Running Shoe has gone from strength to strength, famed for its fast and comfortable performance. This latest edition increases the breathability of the shoe thanks to its Microfit stretch mesh upper with perforations for optimal airflow, keeping your feet cool and your temperature regulated mile after mile. It fits like a second skin thanks to its snug construction and traditional lacing system so your feet remain secure and agile, while a responsive Boost midsole and Lightstrike cushioning give an incredibly plush underfoot experience. Quickly dispersing impact shock with each stride and delivering maximum energy return at toe-off for a comfortable, forward propelling running experience that will push you ahead of the competition. Finished with a Continental™ Rubber outsole for enhanced grip and long-lasting durability.
