The UltraBoost 4.0 ‘Core Black’ puts a Triple Black upper on the fourth iteration of the running silhouette. The black Primeknit upper is matched by the Three-Stripes lacing cage and external heel counter, matched underfoot by the Continental rubber outsole. The Boost midsole contrasts the look in white while providing cushioning.
