Love your feet, love PUMA's planet. The Better Foam Emerge 3D is a women's running shoe that delivers sustainable signature style and comfort while caring for the environment. The lightweight knit upper and sockliner are made using recycled and sustainably-sourced materials. Created using 35% bio-based sugarcane, PUMA's eco-friendly Better Foam midsole not only keeps you light on your feet, but reduces your carbon footprint as well. Last but by no means least, the performance rubber outsole contains a reground rubber component that not only delivers great traction but adds a unique look.
