Chaco is an American footwear brand known for its product line of adjustable Z-strap sandals for outdoor and water use.

He created a pair of custom sandals that included a continuous pull-through strap of synthetic material and a buckle instead of velcro.

By 1991, after making the shoes in a spare room in his house, Paigen began selling his products in a small shop in Glenwood Springs, Colorado.

Chaco created a limited-edition version of the Z/Sandal with 100 percent of the net proceeds being given to a pair of non-profit organizations that fight to protect the monument.
