Phantomcat Nitro Spikeless Shoes The new, waterproof PHANTOMCAT NITRO Golf Shoes feature PUMA's FLEXSPIKE traction system. Reimagined from the ground up, this unique geometry increases the surface area of the cleats, providing ferocious grip and control in all playing conditions. Also, weight is distributed much more evenly, relieving unwanted pressure and discomfort caused by traditional spikes. The PHANTOMCAT is exceptionally comfortable as well, thanks to PUMA's foam technology. Infused with nitrogen, NITRO foam delivers superior cushioning, responsiveness, energy return, and power in the golf swing while remaining lightweight.
