adidas Women's Ultraboost 1.0 Sustain Running Shoes - Energy Return

Our review of the adidas Women's Ultraboost 1.0 Sustain finds a shoe built for runners and everyday wearers who prioritize long-lasting cushioning and a sock-like fit. The single biggest reason to buy is the BOOST midsole, which provides a noticeable, responsive energy return that helps sustain longer runs and long days on your feet. The PRIMEKNIT upper hugs the foot comfortably for adaptive support, while the Continental Rubber outsole gives confident traction on most surfaces. This shoe is a solid choice for those wanting comfort and rebound in a clean, athletic silhouette.

Key Features

• ADIDAS PRIMEKNIT: A foot-hugging knit upper that adapts to natural movement for a snug, supportive fit without feeling rigid.
• BOOST cushioning: Energy capsules fused into the midsole deliver responsive energy return to reduce fatigue during runs or all-day wear.
• TORSION SYSTEM: Built-in support between heel and forefoot helps stabilize the foot during transitions and varied paces.
• Continental Rubber outsole: High-traction rubber provides reliable grip in both wet and dry conditions for safer footing.
• Sustain design: Materials and construction reflect adidas focus on durability and sustainability for longer-lasting wear.

Who It's For

The Ultraboost 1.0 Sustain works well for runners who value cushioning and rebound over a minimal, barefoot feel; it also suits walkers and commuters who spend many hours on their feet and need durable comfort. The adaptive PRIMEKNIT upper supports natural motion, making it a good pick for gym-to-street use and casual training sessions.

Those who need a very wide toe box or prioritize maximum slip resistance should look elsewhere; some customers report a narrower toe fit and occasional issues with grip on slick surfaces. If you require a stiffer, motion-control running shoe for severe overpronation, a more structured model would be a better match.
