History has it that when Mark Paigen designed and made the first Chaco sandal, that a French friend off his described it as Zee One and so that style became the Z 1, and that sandal became an icon, renowned for its durability and comfort with a dedicated following. Fast forward a few years and Chaco brought the Z Cloud to the table, a minimal development that has a thin and soft PU layer for instant comfort. Here at Outsiders we have never worn a more comfortable sandal, I suppose you could count us amongst that dedicated following.
