Nike SB Dunk Low The Powerpuff Girls Bubbles develops the familiar Nike SB Dunk profile through a specific colour treatment and details created for this edition. Bubbles combines a blue base with a yellow Swoosh and enlarged character eyes on the heels. The skate version of the Dunk combines familiar panelling with stronger padding and leaves room for graphics and personal references from each creator. Padding and foam cushioning support comfort, while the rubber outsole grips city streets and skateboard decks.
