Made of a soft leather that ages with wear, it is no wonder why it's been a classic for almost 60 years. Iconic details: Our Jacks Flat showcases our signature whip stitch & rondelle, both details that are done by hand on each pair. Due to this craftsmanship, no pair of Jacks is exactly the same! Leather Footbed: In an ode to the first Jacks made in Italy years ago all of our Jacks Flat Sandals are made with leather footbeds & stitched to the outsole. Over time the natural oils of the foot will change the color of the footbed- this is a detail unique to Jacks!
