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

In this review of the adidas Women's Ultraboost 1.0 Sustain, the bottom line is simple: these are running shoes for someone who wants exceptional energy return and a comfortable, eco-minded upper. The shoe's standout is its BOOST midsole, which delivers a lively, responsive ride that helps keep cadence and momentum on easy runs and daily training. While the knit upper and sustainable Parley yarn offer a modern look and reduced environmental impact, the fit can feel narrow in the toe for some wearers, so sizing and personal foot shape should be considered.

Key Features

• BOOST midsole: Provides high energy return for a springy, responsive ride that helps reduce fatigue on longer efforts.
• ADIDAS PRIMEKNIT upper: Delivers a precision-engineered knit that adapts to foot movement for a secure yet flexible fit.
• Parley Ocean Plastic yarn: Uses at least 50% intercepted ocean plastic in the upper, reducing waste while maintaining performance.
• Stretchweb outsole: Flexes naturally with the foot for smoother transitions and a more energized feel underfoot.
• Continental Rubber tread: Offers improved traction on varied surfaces for more confident runs in mixed conditions.

Who It's For

The Ultraboost 1.0 Sustain is best for runners and active walkers who prioritize cushioning and energy return over minimal weight; it's ideal for daily training runs, recovery outings, and anyone who values a comfortable, sock-like knit upper. The environmental angle will also appeal to shoppers who want performance gear made with recycled ocean plastics.

Those with very wide forefeet or who need maximum slip resistance for wet surfaces may want to try a different silhouette or size up, as some users report a narrow toe box and occasional issues with traction on slick floors. Performance racers seeking a stripped-down, lightweight race shoe should also look elsewhere.

Frequently Asked Questions

Do these shoes run true to size?
Many wearers report a mixed fit; they feel true to size for some but narrow in the toe for others, so trying a half size up may help if you have a wider forefoot.

Is the upper actually made from recycled ocean plastic?
Yes, the high-performance yarn in the upper contains at least 50% Parley Ocean Plastic, with the balance in recycled polyester.

Are these suitable for road and light trail use?
The Stretchweb outsole with Continental Rubber gives confident traction on roads and light trails, but performance on very slick surfaces can vary.
