Chaco sandals feature a curved arch and straps to secure your foot, giving you the freedom and comfort of a sandal without sacrificing support. Chaco sandals can be divided into two basic groups -- those with a loop around the big toe and those without a loop. In either style, the trick to adjusting your Chaco sandals lies in manipulating the straps, which need to be pulled in a specific order. With a little practice, you'll have a fit that's snug but not too tight, and your Chaco sandals should feel comfortably secure all day long.

Loosening Your Sandals
Open the buckle on your Chaco sandal. Pull on the strap that feeds into the buckle to loosen it. This strap sits on the top of your foot nearest to your ankle.
Pull on the strap that crosses from the outside ball of your foot up to your big toe. Tug toward your toes to loosen the strap.
Loosen the strap that crosses over your big toe, or the toe-loop strap, by pulling it away from your second toe. If you have Chaco sandals without a toe loop, omit this step.
Pull the strap that crosses from your pinky toe to the inside arch of your foot and around your heel. Pull toward your arch and away from your pinky toe to loosen.
Tightening Your Sandals
Put your Chacos on. The straps may be loose, but they should not have any twists or kinks. The heel strap should be loose around your heel.
Pull the toe loop lightly toward your second toe, if your Chacos have a toe loop. The strap that crosses from your pinky toe to your arch will tighten. If your Chacos don't have a toe loop, omit this step.
Tug on the strap that crosses from your big toe down to the outside ball of your foot. If your Chacos have a toe loop, it will tighten. If you don't have a toe loop, the strap that crosses from your pinky toe to the inside arch of your foot will tighten.
Pull on the strap that feeds into the buckle of your Chacos. This will tighten the sandal around the top of your foot.
Pull the strap that feeds out of the buckle to finish tightening the shoe, then close the buckle to secure your Chaco. The fit should be snug but not tight, and you will have a small portion of strap that hangs out of the buckle.
