FLAT PLAT But this time FLAT PLAT is more accessible while retaining it's quality. To test the final product, an initial high end and very limited run of the shoes were made in Italy with exotic materials and sold in Arefeh's Worth Avenue store in Palm Beach. Using a US patented outsole for outstanding comfort and support; FLAT PLAT was inspired by Arefeh Mansouri's own discomfort with flat shoes.
