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

In this review of the adidas Women's Ultraboost 1.0 Sustain, the bottom line is straightforward: these are running shoes built for runners who prioritize energy return and a sock-like fit. The combination of a PRIMEKNIT upper and BOOST midsole creates an exceptionally comfortable ride that keeps miles feeling less fatiguing, while the Continental Rubber outsole helps with traction on varied surfaces. They work best for daily road runs and casual wear where responsive cushioning and breathability matter most.

Key Features

• ADIDAS PRIMEKNIT: The foot-hugging knit upper wraps the foot for a snug, adaptive fit that supports natural movement without restricting flexibility.
• BOOST cushioning: The fused energy capsules deliver a lively, responsive ride that returns energy on each stride for lasting comfort over longer runs.
• TORSION SYSTEM: Built-in midfoot support stabilizes the transition between heel and forefoot for a smoother gait.
• Continental Rubber outsole: Durable rubber provides confident traction in both wet and dry conditions to reduce slips on varied surfaces.
• Sustain construction: Designed with sustainability in mind to offer a performance shoe with reduced environmental impact compared with standard builds.

Who It's For

The Ultraboost 1.0 Sustain is best for runners and active walkers who want a plush, energy-returning shoe for daily road miles and gym sessions, and for people who value a knit upper that moves with the foot. Its responsive BOOST midsole rewards those who prefer cushioning that still feels lively rather than dead underfoot.

Those who need a very wide toe box, a completely slip-resistant sole for slick surfaces, or a shoe that is extremely easy to put on and off may want to consider alternatives, as some wearers report a narrower toe fit and occasional issues with pulling the knit upper over the heel.

Pros & Cons

Pros

• Exceptional long-run comfort from the energized BOOST cushioning.
• Adaptive, breathable fit from the PRIMEKNIT upper that reduces hot spots.

Cons

• Fit can run narrow in the toe for some feet, which may cause discomfort for wide-footed users.
• Some customers report reduced slip resistance and difficulty pulling the shoe on compared with simpler designs.

Frequently Asked Questions

Do these run true to size?
Many users find the length true to size, but several report a narrower toe box, so trying them on or ordering a half size up may help those with wider feet.

Are they good for long runs?
Yes. The BOOST midsole provides sustained energy return and cushioning that many runners find comfortable for longer distances.

Will they grip in the rain?
The Continental Rubber outsole offers improved traction in wet and dry conditions, but some customers still note occasional slip resistance issues on very slick surfaces.
