Upper: Microfiber top and nylon mesh upper with air vents. Side Stability Support (3-S) is a set of technical features used in the construction of the upper, which ensure correct support for the foot during sideways movements. Internal Fastening Belt (B-Fast) is an exlcusive Lotto technology for tennis footwear. The internal construction includes a strap system which provides lateral support of the foot, particularly during extreme sideways movements. Reinforce² is the innovative reinforcement inserts in special mixes of rubber and rubber with polyurethane, which are spread in the areas subjected to most wear. Heel Control (HCTL) is a set of technical features used in the construction of the upper to ensure correct heel support and control. 2-Pull is a stiffener of the two top lace eyelets which allows for more vigorous lacing, providing foot stability benefits during play. In addition, with "Cross-Pull" lacing, a better distribution of forces on the instep zone is obtained, with benefits in terms of comfort and fatigue.

Midsole: Syn-Pulse is a revolutionary cushioning system consisting of two elliptical Pebax elements within the shoe's midsole resulting in cushioning, energy return, differentiated cushioning, torsional control, foot arch support with cushioning and lateral movement control. The Adapto System is a heel counter made of TPU whose outstanding elasticity enables it to adapt perfectly to the shape of the heel. Positioned at the read of the shoe, the Adapto System wraps around the heel in an anatomically correct way and offers the twofold benefit of flexibility and support. The harder section at the sides offers stability and support for the heel. The soft and flexible wrap around section at the rear, adapts itself perfectly to the shape of the heel, preventing repeated microtraumas that would otherwise cause tendon inflammation. Total Stability Concept (TSC) provides exceptional hold and stability during the most extreme sideways movements. Removable anatomical EVA insole. Dual EnerTurn (Energy Return), in the forefoot and heel, is a cushioning system of different density elastic materials that disperse the negative forces of impact and returns accumulated energy. Molded EVA midsole. The Dual Fit System provides two interchangeable insoles which allow a personalized fit depending on the intensity of your activity whether it is training or competition.

Outsole: Puntoflex is a special technical device which allows the foot to flex correctly and gives an excellent elastic return. Specialized flex groove placed across the tread in the metatarsal area allows for correct foot flexion and excellent rebound. The DTO outsole has a differentiated traction between inner and outer portions of the tread that is faithful to the different biomechanical functionality of the foot in these two areas providing more traction in the internal part and less traction in the external part. The DTO solution guarantees better ground traction without jeopardizing performance in sliding and rotating movements. All around performance on all types of surfaces. Longlast 30 (LL30) is a special rubber compound with high abrasion resistance. It guarantee a longer lifespan of the outsole on all playing surfaces.
