What are Chacos and why is a good Chacos size important?

Chaco is an American brand of footwear best known for its product line of adjustable Z-strap sandals for outdoor and water use, often referred to as “Chacos”.

The Chaco brand also offers a selection of fashionable sandals, shoes, flip-flops, boots, and accessories with an outdoor influence.

Using a single strap that loops around the foot through the sole and allows for fit change without the use of additional fasteners defines the flagship series of re-positionable outdoor sandals. The manufacturer provides a repair service, and they are available with a variety of sole kinds and strap configurations to suit different conditions.

However, sizing Chacos is much more than just going down to a whole size. The heel-to-ball measurement instead of overall foot length, like most shoe sizes Chacos.
Proper fitting footwear and a well-supported arch are the building blocks of whole-body health, so getting the right size Chacos is super important.

How do i know my Chacos size?

How to understand shoe width with more parameters can be found here.
Find out How to measure your shoe size correctly here.

10 easy steps to measure your feet correctly:

  1. Measure your feet in the afternoon.
    Your feet swell during the day, it’s best to measure your feet at their fullest
  2. Stand When Measuring
    When in a wheelchair there’s no pressure on the feet, so it’s unnecessary to stand up.
  3. Wear socks
    In Chacos sandals you most probably won’t wear socks. But when you plan to, make sure you wear socks when you measure your feet.
  4. Be precise
  5. Measure both feet
    Measure your left and right foot separately as they’re not the same length. Take the biggest measurement to determine your shoe Size
  6. Stand on your piece of paper
    Keeping your body weight over your foot, trace a thin line around the outside of your entire foot.
  7. Start drawing
    When drawing the line, hold the pen perpendicular to the ground.
  8. Measure the length of your feet
    Measure vertically down the length of your foot tracing. This is your foot length.
  9. Find your width fitting by drawing or with measuring tape
    Measure horizontally across the widest part of your foot tracing. This is your foot width.
  10. Determine your Chacos size in the conversion charts
    Start from the measurement in inches or centimeters and define your size in the charts for men, women or kids

Measuring with a Brannock Device

My overall foot length is just a smidge over 8.5 and my heel-to-ball measurement (right arch length on the Brannock device) is just a smidge under 8.5. My foot width is a solid B, narrow to regular width.

What all this translates to with Chacos is that the typical “go down to the nearest whole size” recommendation is correct for me. So my Chaco size is an 8 even though I typically wear an 8.5 in other shoes.

Any well-trained footwear staff should be able to measure all this for you, but you can also measure yourself. The Brannock device has been around for decades as the measuring standard for footwear and is simple to learn to use.

If you are ordering Chacos online, your best bet for getting the right fit is a Brannock device. All shoe stores have one even if they do not sell Chacos. When shopping for Chaco, amazon customers get a free return shipping charge if the item model doesn’t please them.

Frequently asked questions and answers

Does Chacos run true to size?

Yes, Chacos are true to size! If you choose your perfect size, they will give you a cozy fit and make your feet feel very comfortable.

Do Chacos run big or small?

For your ultimate footwear, Chacos have shoe size for all customers. It’s true Chacos run pretty true to size and no wrong size at Chacos.

How to tell the size of Chacos?

On performance sandals, the sizes are on the heels back. Before and after the size, there are dots or dashes that represent the width. Dots and a broad width by dashes show medium width.

How tight should Chacos be?

There should never be a shoe that is too tight or too loose. We advise your Chacos fit snugly and that you always leave enough space for your finger to pass below the webbing. Make cautious not to over-tighten the toe loop on the sandal with the loop at the bottom.

Should I get wide or regular Chacos?

One of Chaco’s all-time top sellers is the chaco Z/cloud sandals. Because of its wonderfully soft footbed, they are a favorite of both sexes. Due to how delicate they are, therefore they are nicknamed Cloud. The footbed’s top layer of ultra-soft PU gives it that comfort. For wide shoes, these Chacos fit well. For a wide foot, the straps are proportionately longer so that they are more adaptable. They appear to drag on a bit.

Do Chaco sandals stretch out?

To stretch out the straps so that they soften up a bit, I suggest you get them really wet as soon as you can. So, walk through a creek or in the crashing waves at the beach. Or, you can just wear them in the shower or use the garden hose on them. Chaco double straps are incredibly easy to adjust when you first get them. But then they stick.


How do I get my Chacos to unstick? 1 part water and 1 they should combine part unscented liquid fabric softener in a bucket. Overnight soak the sandals, then pull the stuck straps straight up where they exit the shoe.

Chillos sport is one of the brand-new Chaco that is doing well. Because of their exclusive offers, the chaco chillos sport sandals are dear to any customer.

Chaco Z clouds, Chaco men’s, and Chaco W feature softer, lighter soles to provide more comfort during extended use outings. People size when purchasing is a factor when getting a good chaco for you. Proper size or the correct size will equate to a comfortable Chaco. The shoe size should be an important factor.

For safer mountain adventures, especially wet adventures, if what is on your foot is a sandal, you should be very careful. According to your adventurous style, a chaco offers you a day of comfort during your recovery time. Because of the outsole technology, Chacos have excellent outsoles which guarantee day comfort.
