Martin Sports Viper Soccer Ball

The Martin Sports Viper soccer ball line provides clear progressions for growing players, featuring the size 4 in silver/red for youth ages 7 to 11 and the size 5 in silver/black for players ages 12 through adulthood. While both models utilize identical durable construction—including an all-weather machine-stitched synthetic leather cover and an air-retaining butyl bladder—they differ precisely in dimensions to match official league standards for their respective age brackets. This makes the Viper series a reliable, budget-friendly choice for families, schools, and leagues transitioning players from junior development up to official adult-sized match play.
