The Flyer Flex expands on the successful Flyer Runner platform and brings a totally new style to PUMA?s flexibility space in DC2. The tooling features a bold new silhouette, with flex grooves running the full length of the tooling. Rubber coverage in the heel and toe provide outsole durability and traction. The upper features a Formstrip branding with a printed outline, as well as heel and eyestay overlays. A bold PUMA branding in the heel rounds out the upper interest.
