Part of Puma’s retro-future Running System collection, the technical RS-X sneaker is remixed with streetwear style with help from Danish brand HAN Kjobenhavn. Released in April 2019, the HAN Kjobenhavn x RS-X 'Black Silver' sneaker consists of a mesh upper with unique rubberized leather and hot-melt overlays. Outfitted with a speckled lacing system, supportive heel counter and reinforced TPU pieces, the upper rests above RS technology for optimal comfort.
