In terms of comfort, Chaco sandals are considered to be the best in the industry. In order to make the most comfortable sandals, Chaco only chooses the most durable materials and uses the most comfortable design. Even when walking on extremely rugged and harsh roads, Chaco sandals are still stable and durable, allowing users to walk as if flying. The comfort and durability of Chaco sandals make them the first choice for white water challengers, including rubber boat pilots who lead tourists to conquer the Colorado River in the Grand Canyon of the United States. From 65438 to 0989, Chaco created the world's first pair of non-hook and loop sandals. Chaco uses a fastener called a "four-speed buckle" to secure the webbing. This fastener has been used on backpacks and other objects before, and Chaco sandals are used on footwear products for the first time.
