Shoe Of The Week: adidas Adizero Boston Boost 6
The updated Boston with Boost midsole foam makes running fast something that just happens.The Boost midsole foam has improved every adidas shoe, and this one is no exception. Made from fused thermoplastic polyurethane pellets, adidas’ Boost midsole material has shown in independent lab tests to be considerably more absorbent and resilient than other types of foam. The new Boston lightweight trainer/racer—which has Boost foam for the first time—is the consummate 10K to marathon racing shoe. This lightweight trainer-racer provides just enough cushioning for a marathon yet the lightness of a racing flat. But with a 10mm heel-toe differential and a near-maximal amount of heel cushioning, the Boston Boost isn’t flat at all—something most of our wear-testers found quite satisfying when running downhill or late in a run. A new airy mesh upper on the men’s (and knitted upper on the women’s) locks down the foot while providing greater breathability, although its narrow, low-volume fit makes it better for racing and fast training than for longer training runs. The Boost foam has enough structure and resiliency that both neutral runners and moderate overpronators will benefit from it. The durable Continental rubber outsole and plastic transition bridge under the midfoot provide a steadiness lacking in more bare-bones racing or performance training shoes. Is there a drawback? Believe it or not, a few of our testers thought this shoe had too much bounce.
This is the shoe for your if … You’re looking for a well-cushoined and very resilient shoe that’s versatile enough for a wide variety of training runs and fast enough for races ranging from 10K to the marathon.
