Cole Haan has refined the Zerogrand silhouette, pushing its materials to the limit to create the lightest shoe imaginable. Ultra-breathable as well, these sporty, chic lace-ups feature an innovative lacing system that locks laces into place so the shoe becomes an effortless slip-on style too. If you have a low instep and prefer a snug fit, we suggest a half-size down. If you have a medium or high instep, order your normal size.WE'VE REFINED THE ZEROGRAND SILHOUETTE, BROADENED THE OPTIONSPUSHED OUR MATERIALS BEYOND THEIR LIMITS TO CREATE LIGHTEST ZERO GRANDINNOVATIVE LACING SYSTEM THAT LOCKS LACES INTO PLACETHE SHOE BECOMES AN EFFORTLESS SLIP-ON STYLEULTRA-BREATHABLE STITCHLITE KNIT UPPERLUXE CUSHIONING IN OUTSOLE, FOOTBED, SOCK LINERSPRINGY ARCHED OUTSOLE ABSORBS SHOCKSMART MATERIALS MIMIC THE FOOT'S NATURAL FLEXIBILITY
