Woven and synthetic fabric on the upper provides a lightweight fit and airy feel. The 270 Max Air unit provides 270 degrees of see-through cushioning. Foam cushioning underfoot feels soft and lightweight. Rubber outsole provides durable traction. The Nike Air Max 270 Big Kids' Shoe is inspired by two icons of Air: the Air Max 180 and Air Max 93. It features Nike's biggest heel Air unit yet for a super-soft ride that feels as impossible as it looks.
