This New Balance 577 Sizing Guide uses direct comparison photos where I put my 577 shoes next to other popular shoes so you can see the difference in sizing. I will also discuss things like weight, width, flexibility, heel drop, and sole height. After trying these shoes, do New Balance 577 shoes run big or small?
New Balance 577 shoes fit true to size for most people. However, some people find that the 577 fits just a little bit smaller than their normal shoe size regarding length. If you are in-between sizes, it may be best to size up.
It’s important to note that this shoe is built using the SL-2 last, which is designed to create a wider forefoot area and a deeper toe box (show me comparison sizing photos for the 577). However, the SL-2 will *most likely* not be wide enough in standard form to overcome the need for wide sizing. In most cases, even on a wider last like the SL-2, you should still order wide sizing if you normally order wide sizing in shoes.
Let’s start this New Balance 577 Sizing Guide by looking at the direct side-by-side comparison photos of my New Balance 577 shoes compared to other popular shoes. Then let’s discuss how other design specs of this shoe differ from other options.

Do New Balance 577 Shoes Run Big or Small?
Although normal sizing worked for me, the New Balance 577 shoes do run just a tiny bit smaller than similarly-styled shoes regarding length. If you are in-between sizes, it may be best to size up. In the next section, let’s discuss the width of these shoes.

Do New Balance 577 Shoe Fit Wide or Narrow?
The New Balance 577 shoe is a leather walking casual shoe built to provide support and stability. It is built using the SL-2 last, which is designed to create a wider forefoot and deeper toe box area.
It’s important to understand that although the SL-2 last creates a wider fit compared to normal lasts, it won’t be enough to overcome the need for wide sizing. You will likely still need to order wide sizing if you normally order wide sizing in shoes. The SL-2 will feel just a tiny bit wider than standard shoes.
To give you a better idea how wide the 577 fits, here is the Balance 577 compared to my Nike Cortez shoes. The Nike Cortez are well-known for having a narrow, shallow toe box (both size 12).
As you can see, the 577 shoe does fit wider than the narrow Nike Cortez. But, again, even though this shoe is a little bit wider than regular shoes, it likely won’t be enough to overcome the need for wide sizing.
To get a better idea of how wide these shoes are, below is the width of my New Balance 577 shoes (standard) compared to the Nike Air Monarch 4E (which is a popular extra wide shoe) both size 12. Please note that the New Balance 577 (on the right) has a midsole that flares out a bit on the right side, which can make it look a bit wider than it really is:
Below is a photo of me measuring the width of the outsole on my 577 men’s size 12 shoes:
As I mentioned above, the design of these shoes has a midsole that flares out a bit (meaning this measurement above won’t give you a perfect indication of the width of the shoe).
How Much Do New Balance 577 Shoes Weigh?
My size 12 men’s New Balance 577 shoes weigh 1.01 pounds per shoe.
Recently I tried over 30 different types of New Balance shoes. Overall, these shoes are one of the most lightweight leather walking shoes made by New Balance.

New Balance 577 On Foot
Here I am wearing my New Balance 577 shoes, which I found to have a true-to-size, comfortable fit:
Are New Balance 577 Shoes Breathable?
The New Balance 577 shoes are not one of New Balance’s most breathable options. It’s important to understand that these shoes are built for for padded comfort and stability. They are made with thick padding for cushioning, and they are made with leather uppers which help provide stability and support.
Here is a close-up look at the material on my 577 shoes:
New Balance offers a wide selection of breathable shoes. Many of their running shoes are very breathable. For example, here is the the New Balance Propel that I own:
You can actually see light passing through the shoe.
But it is important to understand that many New Balance running shoes won’t provide the same level of support and stability that the 577 provides.
If you are looking for a more breathable New Balance walking shoe that also provides stability and support, I would suggest considering the New Balance 847v4 walking shoes. They are made with breathable mesh on the upper, but still have the New Balance ROLLBAR technology for stability and the TPU heel insert for enhanced support.
The main takeaway is don’t expect the New Balance 577 shoes to be the most breathable option. But what this shoe lacks in breathability, it makes up for with stability, comfort, and support.
How Flexible are New Balance 577 Shoes?
Flexibility can play a large role in the fit and comfort of a shoe.
The New Balance 577 shoes have a design that is flexible enough to walk in. But, remember, these shoe are made using leather uppers. They provide more support than lightweight running shoes, but because of that, they aren’t as flexible.
In the videos below I tried to capture how flexible these shoes are:
Do New Balance 577 Shoes Fit Tall?
New Balance 577 Sole Height
I found the New Balance 577 sole height for my size 12 shoes to be approximately 1.5 inches tall near the heel. This heel height is very similar to many other types of New Balance shoes that I have tried.
In the photo below, I tried to capture the heel height, and the overall height of the 577 shoe:
New Balance 577 Heel Drop
When I searched for New Balance 577 heel drop information, I couldn’t find solid data anywhere. New Balance (at the time I am publishing this article) does not list the 577 heel drop information on the product page.
I decided to measure the 577 heel drop myself. When I measured my New Balance 577 shoes using an 8-inch Digital Outside Caliper, I found the heel drop to be approximately 12mm.
Here I am measuring the heel drop of the New Balance 577 shoes:
**It is important to understand that although I tried my best to get accurate measurements, the best way to measure heel drop is to cut the shoes in half and use an industrial caliper. Obviously, I didn’t want to destroy my shoes, but this is a convenient alternative way to measure the New Balance 577 heel drop.
The point is, think of this number as an approximation. For all official measurements, it would be best to reach out to New Balance directly.
The heel drop won’t affect how the New Balance 577 shoes fit, but it can affect how comfortable it is for you to use. To read more, visit my article that discusses the New Balance 577 heel drop and how it compares to other options.

Does the New Balance 577 Have a Removable Insole?
Yes, the New Balance 577 has a removeable insole in case you need to clean or swap your insole. Here is a look at the removable insole in my New Balance 577 shoes:
How Thick is the New Balance 577 Insole?

New Balance 577 Sizing Conclusion
In my experience, the New Balance 577 fits true to size. That said, some people find this shoe to fit slightly small compared to normal shoe sizing. If you prefer a loose fit, you may need to size up a half size.
The New Balance 577 shoes have a regular width that I would describe as not too narrow nor too wide. This shoe is available in wide sizes.
If you are looking for a wider, roomier shoe, I would recommend the New Balance 993.
