The Nike Dunk Low GS “UV Reactive” is a special youth edition of the classic basketball shoe with Swooshes that change color in UV light. One of the more unique Dunk colorways, the “UV Reactive” has a Midnight Navy leather upper with white leather overlays. The Swoosh and heel tab both change color from white to orange when exposed to sunlight. A smiling, sunglasses-wearing sun character graphic appears on the lateral side of the heel.
