Frequently
Asked Questions
Everything you need to know about the UltraBoost 25.
Kinetic Core uses strategically placed responsive capsules within the midsole that work in harmony with the Boost material. When pressure is applied during heel strike, these capsules compress and store energy, then release it during toe-off for a propulsive sensation. The system increases energy return by 15% compared to previous models.
Yes, the UltraBoost 25 fits true to size. The Primeknit+ upper adapts to your foot shape, providing a snug yet comfortable fit. If you're between sizes, we recommend sizing up. For runners with wider feet, consider trying the shoe in person or ordering a half size larger.
With proper care, the UltraBoost 25 maintains optimal performance for 300-500 miles of running, depending on your running style, weight, and surface conditions. The Continental rubber outsole is designed for durability, and the Boost midsole maintains its cushioning properties longer than traditional EVA foam.
The UltraBoost 25 features an adaptive Primeknit+ upper that accommodates various foot shapes. While we don't offer specific wide sizes, many runners with wider feet find the standard width comfortable due to the flexible upper material. For those needing extra room, we recommend trying the shoe in person.
We offer a 30-day risk-free trial. If you're not completely satisfied with your UltraBoost 25, you can return them within 30 days of purchase for a full refund or exchange. The shoes must be in unworn condition with original packaging. After wearing them for a run, we recommend washing them before returning if needed.
