Adidas Ultra Boost 3D Stella McCartney Women's GY4916

Adidas Ultra Boost 3D

Designer High-Fashion Geometry & Infinite BOOST Energy: The adidas by Stella McCartney Ultraboost 3D "Core Black / Signal Orange" Fuse catwalk sophistication with marathon-grade engineering in an avant-garde performance silhouette created in collaboration with British designer Stella McCartney. The GY4916 pairs a stealthy, multi-patterned "Core Black" knit upper with electric "Signal Orange" structural pops along the heel counter, woven accents, and pull hardware. Built atop a full-length, energy-returning BOOST midsole and framed by dynamic 3D-mapped supportive caging, this shoe balances sculptural runway aesthetics with high-performance road dynamics.

Benefits: Engineered for dedicated road miles, boutique studio workouts, high-cadence treadmill runs, and statement athleisure rotations, this silhouette prioritizes endless underfoot energy return, adaptive glove-like foot containment, and eco-conscious construction. The seamless Primeknit upper dynamically expands with the natural splay of your foot during high-impact strikes, eliminating hot spots and chafing. Underfoot, the expanded BOOST pellet core cushions harsh impacts while springing back to propel your forward momentum, keeping legs fresh across extended miles.

Key Features:

• Adaptive adidas Primeknit Textile Upper: Precision-engineered knit that molds to the changing contours of your foot throughout the stride, providing zoned ventilation and flexible support.

• Full-Length Responsive BOOST Midsole: High-density expanded TPU pellet matrix engineered to provide plush, temperature-resistant impact absorption and boundless kinetic bounce.

• Structural 3D Exterior Support Cage: Sculptural midfoot cage designed by Stella McCartney to anchor the laces, lock the arch firmly into place, and prevent lateral rollover.

• Continental™ Natural Rubber Outsole: Hard-wearing rubber perimeter engineered for confident bite across wet and dry road surfaces, gym floors, and painted pavement.

• Eco-Conscious Materials: Incorporates sustainable manufacturing principles, utilizing a minimum of 50% recycled content across at least 20% of the upper's pieces.

• Ergonomic Sculpted Heel Counter: Contoured rearfoot support cradling the Achilles tendon while allowing natural rearfoot expansion during loading.

Buyer Guidance & Fit Profile:

• Who This Product Is Best Suited For: Ideal for fashion-forward runners, high-end gym and Pilates attendees, and luxury streetwear enthusiasts who refuse to compromise between high-level running performance and runway design. Coordinates effortlessly with sleek black compression leggings, designer sportswear bodysuits, oversized tailored raincoats, and vibrant performance crop tops. Not intended for rugged, muddy trail runs or technical mountain scrambles where aggressive deep-lug cleats and rock plates are required.

• Fit & Sizing Determination: Fits True to Size (TTS) to slightly snug, true to the classic sock-like nature of performance Primeknit. The upper wraps the foot with a close, compressive embrace, which feels supportive during dynamic movement. Wearers with broad feet (D+ width) or those who prefer additional volume in the toe box should consider sizing half a size up (0.5 size up) to avoid pressure across the instep and outer toes.

• Recommended Conditions & Activities: Optimised for road running, treadmill sessions, boutique gym workouts, travel, and high-fashion urban walking in dry-to-mild weather. Care Recommendation: Spot clean the knit upper and synthetic cage using a soft-bristled brush or microfiber cloth dipped in lukewarm water and mild technical running-shoe detergent; wipe down the white/black BOOST pellet midsole with a damp cloth after outdoor runs; do not machine wash or tumble dry, as heat and spin cycles break down the structural knit tension and damage the internal adhesives; remove insoles and allow to air dry naturally at room temperature in a well-ventilated, shaded space away from direct sunlight or radiators.
