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.
For sneakers, you may cancel your order within 3 hours of placing it or before it is confirmed by the seller - whichever comes first. If 3 hours have passed from when you placed the order and/or the seller has already confirmed the order, then the order cannot be canceled. If neither have occurred, you can cancel your order first by accessing it via “Track My Order” or “My Account,” clicking “Cancel Order” and following the instructions.
