For the ZERØGRAND Slip On Wing Oxford, we added a bit of innovative disruption to an otherwise businesslike look. From studio to street and around the globe, this little gem is the true definition business on the top and party on the bottom. Snazzy leather uppers have the classic brogue detailing of a wingtip, while white rubber outsoles conceal our proprietary Grand.OS technology - an operating system designed to keep your feet feeling like they're walking on sunshine all day long. Center goring and flexible side walls allow these slip-ons to bend and stretch as you go from Bikram to brunch. Leggings, joggers and denim all complete the look.
