The ninth iteration of our award-winning Clifton franchise has launched, lighter and more cushioned than ever before. Eliminating weight while adding 3mm in stack height, the new Clifton 9 delivers a revitalized underfoot experience with a responsive new foam and improved outsole design. Removing overlays and hotmelts, the stripped back upper has been consciously crafted with a plusher heel, reflective heel panel, and streamlined tongue with single side medial gusset. | Features.
