Women's Ultraboost 1.0 Sustain Running Shoes - Energy Return

In this review we look at the adidas Women's Ultraboost 1.0 Sustain, a road running shoe aimed at women who want a lively, cushioned ride with a strong sustainability angle. The single biggest reason to consider these is the signature BOOST energy return, which gives a noticeably responsive feel underfoot for steady runs and daily wear. The shoe combines a sock-like knit upper with a flexible outsole for natural movement, though buyers should note mixed reports on fit and traction.

Key Features

• BOOST midsole: Delivers high energy return that helps propel each stride and reduces fatigue over longer runs.
• ADIDAS PRIMEKNIT upper: Wraps the foot in a supportive, breathable fit to enhance natural movement and reduce hotspots.
• Stretchweb outsole: Flexes with the foot for a more energized ride and smoother transitions.
• Continental Rubber outsole: Provides improved traction on road surfaces for steadier footing in typical running conditions.
• Recycled materials: Built with yarn made from 50% recycled polyester and 50% Parley Ocean Plastic, contributing to 20% recycled content overall.

Who It's For

The Ultraboost 1.0 Sustain is best for runners and active women who prioritize cushioning and a responsive feel during road runs, daily jogs, or all-day wear. The plush BOOST cushioning suits moderate mileage where comfort and energy return matter more than race-day lightness.

Those who need a roomy toe box, maximum slip resistance on wet surfaces, or a very easy on/off shoe may want to try other models: customers have reported a mixed fit with some finding the shoe tight, and a few mentioning slip resistance and pulling-on difficulty.

Pros & Cons

Pros

• Excellent energy return from the BOOST midsole for an energized ride.
• Comfortable, foot-hugging PRIMEKNIT upper that supports movement.
• Durable outsole design with Continental Rubber for better road traction.

Cons

• Fit can run tight for some wearers, so try before committing to a long run.
• Some customers reported limited slip resistance and occasional foot discomfort.

Specifications

Our Verdict

The Ultraboost 1.0 Sustain is a strong choice for women who want plush cushioning and a responsive ride combined with responsible materials. It offers good value for everyday runners who prioritize comfort and traction on roads, but try them on first if you have a wider foot or require maximum slip resistance.
