adidas Women's Ultraboost 1.0 Sustain Running Shoes - Responsive keep

Our review of the adidas Women's Ultraboost 1.0 Sustain finds a runner-focused shoe that prioritizes long-distance comfort and energy return. Built around the signature BOOST cushioning and a stretchy knit upper, it is best for daily runs, gym sessions, and anyone who values long-lasting underfoot comfort. The main reason to buy is the consistent energy return and supportive fit that keeps stride feeling springy over extended miles, although the fit can feel narrow in the toe for some wearers.

Key Features

• ADIDAS PRIMEKNIT: The foot-hugging knit upper wraps the foot for an adaptive, supportive fit that moves with the foot during runs.
• BOOST cushioning: Energy-returning midsole material provides a responsive, cushioned ride that eases fatigue on longer runs.
• Torsion System: Midfoot support between heel and forefoot improves stability during transitions and foot strikes.
• Continental Rubber outsole: Durable rubber delivers reliable traction in both wet and dry conditions for confident footing.
• Sustain design focus: Constructed with materials and construction approaches that emphasize longevity and consistent performance.

Who It's For

The Ultraboost 1.0 Sustain is best for runners and fitness enthusiasts who prioritize plush, responsive cushioning and a sock-like upper for daily training, recovery runs, or all-day wear. It suits those who value comfort and a smooth, springy ride over harsh responsiveness.

Shoppers who need a very wide toe box, maximum slip resistance for slick surfaces, or a shoe that is extremely easy to pull on may want to look elsewhere; multiple users noted a narrower toe fit and a tendency to be harder to slip on, and some reported reduced traction in certain conditions.
