Withlight weight comfort in mind, Fila offers the r4. Resembling its more performance-oriented big brother, the r8, the r4 offers more mesh in the upper along with added cushion around the heel collar for better breathability and comfort. Adding to the comfortable fit, the SUPERACTION EVA in the midsole provides excellent underfoot cushion to ease the harsher landings. These aspects offer "step in" comfort for instant playability with no break-in. The beefy EverGrind outsole offers the durability needed for hard court enthusiasts while the modified herringbone pattern provides sure footed traction on multiple surfaces.
