Air 360 is the largest Air sole ever constructed. It was the first time the technology full replaced all of the foam midsole. The 360 technology is adjusted by shoe size for precise impact protection customized to the specific area of the foot and the specific sport involved. It reduces weight and increases durability while providing great cushioning, protection and comfort. Personally while the first gen 360’s were comfortable I found them to be a tad stiff.
