PUMA delved into the archives and brought back a classic from their '80s running styles. The RX 737 stays true to the look and feel of its predecessors, with a lightweight construction, supportive heel cage, and cut out designs on the upper. The PRM edition oozes class from every angle, from the premium leather upper and the meticulous perforations to the gleaming metallic branding. Who said sneakers can't be sophisticated?
