In the 80s, Puma pushed performance innovation with its 'RS'—which stood for 'running system'—technology, and the RS-X Toys 'Blue Atoll' recaptures the heritage, adding a look inspired by toys from the same era. RS -X branding lands on the tongue, and an embossed patch can be found on the heel. Several vibrant overlays top the mesh upper and exaggerated foam midsole, which features three boldly colored plugs to add to the chunky look.
