The original Slip-On TRK was born from purpose, a direct ask from our global surf team to explore what a shoe sandal might look like. Our designers got to work, and the end result was a one-piece, fully rinseable, easily packable shoe that could be worn in a variety of environments. In this latest iteration of the world's #1 beach shoe, We've chopped off the heel cup and improved both the fit and function of this utilitarian style. Meet the Slip-On Mule TRK.
