The Adidas Ultraboost 5X delivers performance that justifies its reputation, even at full price. Runner's World editors rank it among their favorite shoes for both running and walking, a dual functionality that appeals to athletes who want versatility in their footwear rotation.
The Ultraboost line leverages Boost cushioning technology, which provides responsive energy return during ground contact. This matters because the foam absorbs impact forces while propelling you forward with minimal energy loss. The shoe works across different paces, from easy recovery runs to tempo work, without feeling sluggish or overly soft.
What makes the Ultraboost 5X stand out for walking is its balance between cushioning and stability. The midsole doesn't compress excessively under body weight during slower movement, so your foot stays supported without the shoe feeling mushy. The upper construction provides a secure fit that prevents excess heel slippage, a common complaint with cushioned trainers during walking.
The current 50% discount brings the Ultraboost 5X into competitive pricing with entry-level trainers, which shifts the value equation significantly. At this price point, you're accessing premium foam technology and proven durability at a mid-tier cost.
Ultraboost shoes typically log 300-500 miles before noticeable cushioning degradation occurs. That lifespan makes them cost-effective for runners who train regularly. The rubber outsole wears predictably, holding grip on both pavement and light trail surfaces.
The fit runs true to size for most runners, though those with narrow feet sometimes prefer the snug lockdown of earlier Ultraboost iterations. Wide-footed runners should test the shoe before committing, as Adidas doesn't produce a wide version of the 5X.
The discount applies across multiple colorways and sizes, making this an opportunity to stock a backup pair
