New Balance vs Adidas Sizing [Are They True to Size or Not]

Written By Sunny

You have to know the size of your shoes to get the perfect fit. Whether you are looking for a go-to versatile New Balance sneaker or Adidas Ultraboost 22 running shoes, the sizing matters.


In this contest, I will explain how Adidas sneakers’ size differs from New Balance shoes and how you can choose the best-fitted pair for yourself.

So stay put and tag along.

Adidas Shoe Sizing vs New Balance

Though both New Balance and Adidas are good quality, affordable and comfy, regarding sizing there are some notable differences.

New Balance sneakers follow a half Size conversion between US and UK sizes. Adidas also follows the same, but only for US and UK sizes. Adidas differs in EU and CM sizes.


If you look closely, you will find major brands like Nike and Reebok features a UK-US shoe size conversion difference of one.

For example, a US 11 Nike is UK 10. Similarly, a US 8 Reebok is a UK size 7. It’s clear that there is only one size up or down.

However, when it comes to New Balance shoes, a US 9 converts into UK 8.5, the difference is 0.5. So, now the main confusion arises, how to solve this sizing issue when switching across brands?

All you have to do is, forget those old measurements and follow the CM/JP size as a standard.

Why? Let me clarify.

Among every process, only CM represents the true stick length of the shoes. For instance, a Nike US 10 converts into CM 28. So to buy a new shoe, you just need to buy 28 CM and you will be all good.

This size variation also occurs due to the models. You won’t feel the same wearing, a narrow, wide, and standard fitted sneaker. The size chart is the best solution to find a perfect fitted seeker, whether it’s Adidas or New Balance.

Do Adidas And New Balance Fit the Same

No, New Balance tends to fit a few millimeters bigger than Adidas. Men’s New Balance US 3.5 and Adidas US 3.5 has a 9-millimeter difference. So, if you get the same size from any of the brands, your Balance sneakers will be a bit bigger.

For a more snug fit, you can choose the same size Adidas compared to your New Balance.

The fitting is not only crucial for your sneakers, but also your work shoes need to fit your criteria.

Do New Balance Run Big or Small

New Balance shoes run true to size. So, you don’t have to change your size while buying these high-quality sneakers. Get your regular size, and you are good to go as soon as they come out of the box.

Note: Some shoes may have specific sizing notes, so choose each pair carefully to achieve a proper fit.

New Balance also offers in-between sizes, so if you are in search of a proper shoe, you need to check the size chart.

Anyway, if that doesn’t help, go for one size bigger pair. Wearing socks also helps with the sizing issue.


There is no denying, both Adidas and New Balance are excellent choices if you are looking for quality along with comfort. These sneakers will fill up every criterion you want.

But when it comes to sizing, Adidas has its own size chart and if you are ok with that, you have nothing to worry about.

On the other hand, if your feet are in between sizes, New Balance has got you covered with their narrow, standard, and X-Wide.

So, you can select according to your need. Because in both cases it’s a win-win situation.
