A pair of men's nike air max 90 retro sports shoes in darkgrey and blue .
How does Air Max work? Max Air is big air designed to take a pounding. Maximum impact cushioning. The brutal, repetitive, downward force of sport can wreak havoc on the body and on performance. Max Air cushioning is specifically engineered to handle these impacts and provide protection. Look at your own sports shoes. They are so stiff and you definitely can feel them on your feet. But the Nike Air Max90 can solve the trouble from other shoes. If you purchase this Nike model as a replacement, I must say you make a bright choice.
