Upper Construction & Fit
-
The upper is made from breathable textile mesh, reinforced with synthetic overlays and molded TPU components for structural support.
-
High-wear areas, such as the toe box and medial side, are protected by abrasion-resistant materials designed to handle aggressive court movement.
-
A padded heel collar and tongue work in tandem with the anatomical last to provide a secure, locked-in fit that enhances control during quick lateral transitions.
-
The upper delivers both ventilation and containment, making it suitable for long matches and high-intensity play.
Midsole & Stability System
-
Features Surge 7.0 cushioning—a responsive midsole foam engineered for energy return, shock absorption, and long-lasting comfort.
-
The shoe includes a 360° Plantar Support Chassis, a molded TPU system that wraps the midfoot and arch area to prevent torsional movement and improve stability.
-
A Shock Frame TPU heel counter is integrated into the rearfoot for added impact protection and heel lockdown, supporting explosive push-offs and abrupt stops.
Outsole & Traction
-
Constructed with Aosta 7.0 high-density rubber, known for its durability and court grip on a variety of surfaces.
-
The outsole tread pattern varies depending on the version (clay or all-court), with herringbone grooves or multi-directional lugs for optimized traction and sliding control.
-
Reinforced with DragGuard 7.0 technology in the toe and heel areas to enhance durability in high-abrasion zones, especially useful for baseline players and toe draggers.
Performance & Intended Use
-
The Ultrashot 4 is engineered for serious competitors and advanced-level players who prioritize stability, durability, and impact protection over ultra-lightweight speed.
-
It excels during extended rallies, lateral duels, and hard court play, where the enhanced support system minimizes fatigue and risk of injury.
-
While slightly heavier than some speed-oriented models, it offers a planted, confident feel that supports aggressive movement and court coverage.
-
Ideal for players who require a shoe that holds up under pressure, supports powerful footwork, and maintains comfort across long sessions.
