Puma claims to produce the lightest Tour-grade performance golf shoe available. With its stripped-back, ‘seamless' design, less materials are used to make the Swing Crown GTX than in other golf shoes, while it is TPU reinforced for strong support. The Swing Crown GTX features Puma's Smart Quill technology, which consists of a system of quills on the sole rather than spikes, which are strategically positioned to provide ‘ultimate traction'.
