PUMA Men's Tazon 6 Fracture FM Cross-Trainer Shoe is well crafted, looks sharp, and is light. Its insoles are absolutely lovely. Puma uses a material called “soft foam” and mimics memory foam to a degree but is light, cool, and molds with your feet over time. You can wear them as a daily shoe, on work, in the evenings, and they are great for that purpose.
