Women's Ultraboost 1.0 Sustain Sneaker - Boost Energy Return

Our review of the Women's Ultraboost 1.0 Sustain Sneaker finds a shoe aimed at runners and everyday wearers who prioritize cushioning and environmental responsibility. The single biggest reason to consider these shoes is the signature BOOST energy return, which gives a lively, responsive feel underfoot that makes long runs and all-day wear noticeably easier. While fit can run tight for some, the combination of a Primeknit upper and a Stretchweb outsole with Continental Rubber creates a polished package for those who want a lightweight, supportive ride with recycled materials in the construction.

Key Features

• BOOST midsole: Provides sustained energy return on each stride to help reduce fatigue during runs and long days on your feet.
• Primeknit upper: Delivers a precision-engineered, flexible fit that adapts to foot movement for a secure yet comfortable hold.
• Parley Ocean Plastic yarn: Uses at least 50% intercepted ocean plastic in the upper, lowering environmental impact while maintaining performance.
• Stretchweb outsole: Flexes naturally with the foot for a springy ride and pairs with Continental Rubber for improved traction on multiple surfaces.
• Lightweight construction: Keeps overall weight down so the shoe feels responsive and easy to move in across runs and daily activities.

Who It's For

These Ultraboost Sustain sneakers are best for women who want a high-cushion running shoe that still feels lively, and for shoppers who value recycled materials without sacrificing performance. They suit daily trainers, casual runners, and anyone who stands or walks for long periods and wants persistent energy return from their footwear.

Runners who need an especially wide fit or maximum slip resistance should consider alternatives, since customer feedback includes mixed notes on fit and isolated reports of slip-related issues. Those with severe foot pain should try on the shoes and assess comfort before committing.
