Puma's Thunder Spectra 'Steel Grey' sneaker is a modern take on the brand's heritage 90s runners. With design characteristics inspired by 90s Cell System running silhouettes and the Puma x McQueen collaboration, this sneaker is sure to turn heads. The breathable mesh upper with suede and leather overlays provides both style and comfort, while the midfoot stabilizer and cushioned outsole offer superior support and cushioning.
