The new midsole material, aptly named DNA Tuned, is the latest iteration of nitrogen-infused foam that’s designed with different-sized cell technology (larger in the heel for soft landing and smaller in the forefoot for more bounce). It also features a construction similar to rim and core, except both the rim and core of the midsole are adhered together before the foaming process to create a seamless bond. The Max comes into play with just how much of that DNA Tuned they placed underfoot: 45 mm in the heel and 39 mm in the forefoot, for a 6 mm drop. A fairly dramatic Glideroll rocker and plenty of rubber on the outsole finish off this highly cushioned trainer.
