Chaco Sizing

Chacos are available in U.S. whole sizes and have moderate arch support, with most styles offered in both medium and wide widths. In the performance sandal collection, we typically recommend sizing down to the next whole size if you are a half size. In the flip collection, we typically recommend sizing up to the next whole size if you are a half size.

Sizes on performance sandals are located on the back of the heel. The width is indicated by either dots or dashes before and after the size. Dots indicate a medium width and dashes indicate a wide width.

If you would like to discuss size, give us a call. We can advise you as to probable size, but the final decision is yours. Don't forget our two month Test Walk, which lets you try your footwear for up to two months.
