Our Made to Order Picasso Mules are handmade using a 700-year-old Turkish shoe making technique, in Gaziantep, Türkiye, where they've been making shoes for generations. They are made using five different kinds of leather and woven together with cotton thread dipped in beeswax. You want your Nida Lu shoes to start off tight, with your toe at the end of the shoe, it won't take long for the shoes to mold to your foot also creating natural arch support.
