Year after year, the Ghost earns its place as one of the running shoes out there, and the Ghost 18 continues that tradition with meaningful updates that make a great shoe even better. Nitrogen-infused DNA Loft v3 foam delivers a consistent, protective ride that feels balanced and stable underfoot, and reliable in the way that matters most when you're logging the kind of everyday miles that build a real running base. A new Ortholite X-60 sockliner adds a noticeably plusher step-in feel that longtime Ghost fans will appreciate right away. The biggest upgrade in the Ghost 18 is the new engineered air-mesh upper — more breathable, more accommodating and more comfortable than the previous version. A flat-knit tongue, plush heel collar and slightly roomier toe box work together to create a step-in feel that our wear testers couldn't stop talking about. "The upper of the Ghost 18 is what most other brands aim to create," said our reviewer Max. "The step-in feel is unmatched." Whether you have narrow feet, wide feet or something in between, the Ghost 18 makes room for everyone.
