Kids' Nike Big Kid Air Max Invigor Print Running Shoes The Nike Air Max Invig PRT GS is a grade-school running sneaker built around a bold printed textile upper and Nike's visible Air cushioning. The upper carries an all-over graphic print with a gradient fade across the profile, and the Nike Swoosh is integrated seamlessly into the midfoot overlay. A large visible Air Max unit sits in the heel, supported by a chunky segmented outsole designed for everyday traction and impact absorption.
