The Top Flex 903 combines high performance and flexibility with fit and stability. The cut is made of highly flexible leather combined with nylon for lightweight action on the court. PROTECTION technology is incorporated in the toe to reinforce durability and stability for striking. A natural EVA improves cushioning by absorbing the impact of the tread. Pre-molded EVA footbed that fits the last of the foot. The sole is constructed of our DURABILITY technology using high resistance rubber that delays abrasion wear and extends the life of the shoe. The midsole has a system of flex lines, using our FLEXO technology, which are ergonomically designed to give the best transition from the heel to the toe in each step. The heel cup allows for flexion only in the sole, without affecting the cut, which provides a better support and more natural feel with comfortable tread. Our ROTATION syste, a geometric structure located on the sole that facilities rotational turns therefore minimizing knee and ankle injuries.
