Our lightest ZEROGRAND yet. Generation ZEROGRAND Stitchlite uses our proprietary Stitchlite, a stretchy supportive knit, as its main material, then engineers the rest of the shoe with a cushioned footbed, and unbelievably lightweight molded outsole. You'll also notice we put tabs at the instep and heel for easy on/easy offcreating a shoe as light and easy to pull on as a sock.FOR BEST FIT - If you have a low instep and prefer a snug fit, we suggest ordering a half size down. If you have a medium or high instep, order your normal size.
