adidas Ultraboost 1.0 Sustain Running Shoes - Responsive Cushioning is

In this review of the adidas Ultraboost 1.0 Sustain Running Shoes, the bottom line is simple: these are best for runners and daily walkers who prioritize long-lasting cushioning and a snug, adaptive fit. The standout reason to consider them is the combination of BOOST cushioning for energy return and the foot-hugging PRIMEKNIT upper that moves with the foot, delivering comfort over longer runs or all-day wear. They balance comfort and traction, though potential buyers should note fit can run narrow in the toe for some feet.

Key Features

• ADIDAS PRIMEKNIT: A foot-hugging knitted upper that adapts to natural movement and reduces pressure points during runs and daily wear.
• BOOST cushioning: Energy-returning midsole technology that maintains responsiveness and comfort over time for longer sessions.
• TORSION SYSTEM: Midfoot support that stabilizes the ride between heel and forefoot to help maintain a controlled stride.
• Continental Rubber outsole: Durable outsole compound offering reliable traction in both wet and dry conditions for confident footing.
• Sustain construction: Designed with a focus on more sustainable materials while retaining the Ultraboost performance characteristics.

Who It's For

The Ultraboost 1.0 Sustain is aimed at runners who want a comfortable, responsive shoe for daily training runs and recovery days, plus anyone who spends long hours on their feet and values cushioning and arch support. The knit upper and BOOST midsole make it a strong pick for those who prefer a flexible, sock-like fit paired with lively cushioning.

Shoppers with wide toe boxes or those needing maximal slip resistance for slick surfaces should consider alternatives, as some customers report a narrow fit in the toe and occasional issues with traction. Also, users who need an easy-on slip-on style may find the snug PRIMEKNIT harder to pull on compared with simpler designs.

Frequently Asked Questions

Do these run true to size?
Many users report a generally true fit but some find the toe area narrow, so try before you buy if you need extra width.

Are they good for wet conditions?
The Continental Rubber outsole provides improved traction in wet and dry conditions, but a few customers noted occasional slip resistance concerns on very slick surfaces.

Is the upper easy to get on?
The PRIMEKNIT upper offers a snug, sock-like fit that can feel tight to pull on for some; it is supportive but not as easy to slip on as looser-styled shoes.
