The Ghost 8 hits the trifecta of balance, cushion, and light weight. New engineered mesh upper offers improved fit and function, giving you structure where you need it and breathability where you want it. Plus the upper is now virtually seamless, giving you an even more comfortable, sock-like fit. It's been updated with a new full-length Segmented Crash Pad for ultra-smooth heel-to-toe transitions while it still boasts Omega Flex Grooves for optimized flexibility. BioMoGo DNA in the midsole offers adaptive cushioning and responsiveness. It all comes together to make the Ghost 8 a scary good ride.
