adidas Ultraboost 1.0 Sustain Women's Running Shoe - Energized Comfort

In this review of the adidas Ultraboost 1.0 Sustain, the bottom line is simple: this is a cushioned, energy-return running shoe best suited for women who prioritize comfort, responsiveness, and sustainability in everyday training and road runs. The single biggest reason to buy is the BOOST midsole, which delivers a noticeable return of energy underfoot for a lively stride without feeling harsh. While fit varies among wearers, the shoe's blend of a foot-hugging upper and a responsive outsole makes it an appealing option for runners who value ride quality and eco-conscious materials.

Key Features

• BOOST midsole: Provides high energy return for a responsive, springy ride that helps reduce fatigue on longer runs.
• ADIDAS PRIMEKNIT upper: Wraps the foot in a supportive, sock-like fit that moves with the foot to reduce hotspots and distraction.
• Stretchweb outsole with Continental Rubber: Flexes naturally with the foot for a smoother transition and offers superior traction on road surfaces.
• Sustain materials: Upper yarn combines recycled polyester and Parley Ocean Plastic to reduce waste while maintaining durability.
• Lightweight construction: Designed to feel light on the foot, which helps with turnover and daily wearability.

Who It's For

The Ultraboost 1.0 Sustain is ideal for women who run on roads and want a plush, responsive daily trainer that emphasizes comfort and energy return. It suits runners who appreciate a snug, supportive upper and value products made with recycled yarn and Parley Ocean Plastic.

Runners who need a very wide fit, extreme slip resistance on wet surfaces, or those prone to forefoot pain from a tight toe box should be cautious; some customers reported the shoe runs tight for their feet and experienced foot pain or difficulty putting the shoe on, so trying them on or sizing up may be necessary.
