FJ SuperLites deliver a performance ultralight feel with sporty appeal. PU (poly urethane) linings look and feel like leather and provide excellent fit and comfort. The Stinger golf spike offers superior traction throughout the entire golf swing. This golf spike also provides stability and support from the moment you step foot on the course. Unlike traditional spikes, its spring-flex traction makes the Stinger extra friendly to the greens. This ultra-lightweight EVA (ethyl vinyl acetate) outsole provides lightweight underfoot comfort while TPU (thermoplastic urethane) inserts provide additional durability.
