The brand new FootJoy Pro SL Carbon is the ultimate players spikeless shoe that combines a soft and comfortable waterproof upper with a midsole/outsole unit that also features Carbon Fibre for tour level stability. This all comes courtesy of a proprietary polymer outsole material called Fine-Tuned Foam (FTF), which is 10% lighter than conventional EVA foams and provides enhanced cushioning and shock absorption for added comfort. Comprised of three layers of different densities fused together, FTF is the key material to ensure that Pro SL delivers comfort and stability. The top layer that cradles the foot is a softer durometer to provide all day comfort, while the lower portion is firmer to deliver perimeter stability around the foot for maximum support throughout the swing.
