In its fourth iteration, this 4040 is lighter and more flexible and supportive than its predecessors without losing any of its durability or style. The leather and synthetic mesh upper is made tough enough to stand up to any competition, and the REVlite midsole has an integrated medial post for unbelievably lightweight, responsive cushioning and support from the first over of the day to the last. The 4040 bowlers' spike is built with advanced support and cushioning to help ensure optimal performance for long days in the field. An evenly dispersed spikeplate reduces underfoot spike pressure so that the fast bowler can perform longer. Innovative REVlite midsole provides premium responsiveness and durability at a 30% lighter weight than other foams with comparable performance. Leather upper.
