The Puma RS-X Harddrive Grey Yellow Red is a running sneaker by Puma which combines a retro aesthetic with modern technology to offer the best of both worlds. The shoes have a predominantly grey upper with striking accents of yellow and orange on the sides and collar area respectively. There is also a touch of black around the heel to add some contrast to the overall design. The Puma RS-X Harddrive also has a chunky sole unit with a black and white midsole, and multicolored outsole. It uses Puma’s RS-X technology in the midsole to provide cushioning and added support to your feet. One thing that stands out on the Puma RS-X Harddrive Grey Yellow Red is the layered upper which combines different materials such as mesh, leather, and synthetic overlays. This contributes significantly to the overall aesthetic of the shoes, while also enhancing durability. The shoes were first released for retail on 30th June 2019 priced at $110.
