How Should Chacos Fit?

 are globally popular as the most comfortable sandals there are. With their polyester webbing and cork bed midsole, they have emerged as the softest sandal. They are stylish and sturdy and can be worn for everyday activities easily and with a snug feeling. It is very easy to tell when the Chacos are the right fit or not. If your toes are not pushed out of the sandals, or there is little to no space in front of your toes and the straps of the sandals are not wearing down on you then it means that the Chacos you have chosen are the right fit.

If you feel even the slightest discomfort while walking or light running, then it is an indication of them either in need of some time to break in or simply that they are not the right fit. The straps of the sandals are not meant to push down on your foot at all. They must feel comfortable and lightweight on your skin. Additionally, the arch should support your ankle snugly and you must feel comfortable and supported after wearing them.

Chacos Wide vs Regular or Medium – Which Size Should I get

 Going for either wide or regular or medium Chacos is a very personal and subjective choice that solely depends on the shape and size of your foot and whatever will feel comfortable wearing. The choice between width or regular Chacos might come easier into consideration with certain factors like heel cup and arch support. They might offer certain subtle differences that you might feel upon wearing and you can keep them in mind before going for either wide or regular Chacos.

Heel Cup:

Chacos use patented LuvSeat Footbed which provides certain depth to the heel hereby letting them settle in comfortably. This depth gives the foot a snug feeling and also enough space as well for the feet to breathe and slide as well as move around a little. But the space that comes with the depth of the heel might reduce the stability that is otherwise offered by Chacos.

Arch Support:

Arch support is extremely important when it comes to sandals. As these sandals are functional for everyday use, it only makes sense to reduce the discomfort to the minimum. If you go for narrow Chacos, then there is a possibility of them pushing into your arch which will be troublesome while walking. With narrow Chacos, you will also have the problem of tight straps which again might cause discomfort.

Should I Go for Chacos Sizing Up or Down?

Size has been made quite universal with all the popular brands, so getting confused with the sizing of brands like Chacos, whose sizes differ slightly is understandable. Chacos distinction stems from the unavailability of half sizes within their brand. They only have full sizes and thus a person with a size 8.5 has to ponder whether to buy a size bigger or a size smaller. The debate about whether to size up or down has been going on for too long and people are equally divided between the two. Some reviewers say that you should always size down whereas some reviewers say you should almost always size up.

Sizing down is recommended for a snugger and narrow fit whereas sizing up is recommended if you are focusing more on your arch support. There is no method to sizing up or down as it varies from person to person depending on their foot size and shape but any wrong size is bound to discomfort you.

Chacos keep their straps slightly free for them to naturally adjust to your foot shape and size making the comfort optimum for you.
