The Petra is an ideal city sandal. In other words, this is a shoe that can handle cobblestones, subway grates, and walking a few extra blocks.The wood flatform is a walkable height that keeps some distance between your foot and the sidewalk, while the wide leather crisscross straps and adjustable buckle ensure a secure fit. We used a super-soft leather for the upper and added 4mm of foam to the insole for all-around comfort, and we finished it with nailhead trim for a cool, 70s-inspired vibe.
