Frequently Asked Questions
Is the UltraBoost Runner X good for flat feet?
Yes. The UltraBoost Runner X features a Torsion System midfoot support that provides excellent arch stabilization. Runners with flat feet report improved comfort compared to neutral shoes without structured support. We recommend pairing with a custom insole for maximum support.
How does the UltraBoost Runner X compare to previous models?
The Runner X features 15% more energy return than the UltraBoost Runner V, a 20g weight reduction, and improved breathability through a redesigned mesh upper. The Continental rubber outsole now offers 30% better wet traction.
Can I use the UltraBoost Runner X for marathon racing?
Absolutely. The UltraBoost Runner X is designed for distances from 5K through full marathon. Its energy-return foam reduces fatigue over long distances, and the 280g weight keeps it competitive with dedicated racing flats while providing superior cushioning.
