BIRKENSTOCK GIZEH 743831 OILED HABANA LEATHER Size:41 Some people like to wear Some people like to wear the straps loose but we recommend at least keeping the strap across the ball of your foot fastened snug so your foot is held in place and doesn't move back and forth when you walk skin friendly The Birkenstock Gizeh is a comfortable thong sandal with a toe post that has been specifically developed for this deep foot bed: it is anatomically shaped and fits gently between the toes guiding them back to their natural position They have a visible grain and naturally occurring colour irregularities that are deliberately not removed in production in order that the natural matt surface of the leather is preserved
