The BIRKENSTOCK Lutry can be worn as a backstrap style or as an open clog thanks to the flexible ankle strap. The footbed can be removed so that you can choose between three different footbed versions. This basic version of this design features our Standard Footbed. It replicates the natural print made by a foot walking on sand and will see you through the day in comfort. Its natural design is down to the upper made from especially soft suede, which hugs the foot like a second skin.
