AIR JORDAN 4 RETRO INFANT/TODDLER BOYS' SHOE (2C-10C)
FEATURED TECHNOLOGY
NIKE AIR
More than 30 years ago, a revolutionary idea raised the standards in sneaker comfort: Use the lightest cushioning material there is—air. Nike Air units work by trapping air molecules inside a durable urethane shell. With each footstrike, the air unit compresses to reduce the force of impact, then immediately recovers its shape to be ready for the next landing. Nike Air units are built to last, so the cushioning properties hold steady for the life of the shoe.
