adidas Ultraboost 5X "Triple Black" ‘Core Black / Core Black / Cloud White’

The Ultraboost 5X represents Adidas's continued refinement of one of running's most recognizable platforms. Launched as an evolution of the original Ultraboost line that debuted in 2013, the 5X model strips away excess complexity while retaining the DNA that made the silhouette a crossover staple in both performance and lifestyle contexts. The shoe is engineered for neutral runners seeking responsive cushioning without sacrificing ground feel, though its aesthetic appeal extends well beyond the track—the clean lines and minimal visual clutter have made it a favorite among those who prioritize function-first design.

The Ultraboost 5X is built on Adidas's proprietary Boost midsole technology, a thermoplastic polyurethane foam that delivers exceptional energy return and durability across repeated impact cycles. The upper utilizes Primeknit construction, a knitted textile that adapts to foot shape while maintaining structural integrity, paired with a supportive heel counter for lateral stability. The Continental rubber outsole—Adidas's signature high-grip compound—provides reliable traction across varied surfaces, a detail that explains the silhouette's longevity in a market saturated with trend-driven alternatives. The overall package weighs considerably less than its predecessors, a refinement that speaks to Adidas's commitment to lightness without compromising the cushioning properties runners expect from the Boost platform.

The 5X's design language works across monochromatic palettes and bold colorway treatments alike, making it equally at home in minimalist fits anchored by neutral tones or contemporary streetwear builds that emphasize tonal blocking. The shoe pairs naturally with technical running apparel, joggers, or tailored trousers—its versatility stems from proportions that avoid aggressive flare or overbuilt aesthetics. This flexibility has solidified its place in the broader sneaker conversation, where runners and lifestyle enthusiasts increasingly demand shoes that transition seamlessly between functional and social contexts.

At $100.80 after a 44% discount—down from the standard $180 retail price—the Ultraboost 5X represents meaningful savings on a shoe that typically holds value across seasons.
