adidas Women's Ultraboost 1.0 Sustain Running Shoes - Recycled Upper

In this review of the adidas Women's Ultraboost 1.0 Sustain Running Shoes the bottom line is simple: these are best for runners and walkers who prioritize cushioning and sustainability in a daily trainer. The defining reason to buy is the BOOST midsole that delivers pronounced energy return and a lively ride, paired with an upper that contains at least 50% Parley Ocean Plastic for lower environmental impact. Fit can be mixed, so shoppers who need a wide toe box should try them on first, but anyone seeking comfortable, cushioned runs with a performance knit upper will appreciate what these shoes offer.

Key Features

• BOOST Energy Return: The fused energy capsules in the BOOST midsole provide lively, consistent cushioning that helps maintain momentum on runs and long walks.
• ADIDAS PRIMEKNIT Upper: A precision-engineered knit offers a snug, adaptive fit that moves with the foot for a more natural feel during dynamic movement.
• Parley Ocean Plastic Construction: The high-performance yarn contains at least 50% reimagined ocean plastic, reducing waste while retaining durability and structure in the upper.
• Stretchweb Outsole with Continental Rubber: A flexible Stretchweb design pairs with Continental Rubber for improved traction and a responsive transition underfoot.
• Lightweight Design: The combination of knit upper and responsive midsole keeps overall weight down, making the shoe comfortable for extended wear.

Who It's For

The Ultraboost 1.0 Sustain is aimed at women looking for a plush daily trainer that blends comfort, energy return, and a sustainability angle. It works well for runners who favor cushioning over a firm, race-focused platform and for commuters who value grip and a soft ride on hard surfaces.

Shoppers who require a very wide toe box, maximum slip resistance for wet conditions, or who are prone to foot pain from tight toe space may want to try these on carefully or consider models with a roomier fit or additional stabilization features.

Our Verdict

The adidas Women's Ultraboost 1.0 Sustain is a strong choice for runners and everyday wearers who prioritize cushioning, a springy ride, and a more sustainable upper material. It represents good value for anyone wanting exceptional energy return and a comfortable knit fit, but buyers with wide forefeet or those sensitive to slipperiness should test fit and traction before committing.
