If you've ever bought a pair of sneakers that's your size and noticed that your foot feels like it's slipping, this guide to brands that run larger will help you understand why and prevent it from happening again.
Not all brands measure the same. The shape changes, the material changes, and the feeling changes when you wear them. If you keep reading, we'll give you some tips to avoid this again, and to discover which models tend to run larger than normal.
Why do some brands size differently?
Sizing differences aren't due to manufacturing errors, but rather to design issues . Each brand defines the structure of its sneakers based on aesthetics, comfort, and intended use.
Some people prefer a looser fit for greater comfort, while others opt for a tighter fit that provides support. Factors such as the type of activity they're designed for, the material , and even the country of manufacture influence the final feel you'll get when you wear them.

In some models, the toe box is longer or wider , leaving extra room in the front. In others, the insole is more generous in length and width, which means that even if the marked size is yours, the shoe feels more spacious.
It's also common for retro-inspired styles or those designed to be worn with thicker socks to have a more relaxed fit , giving us a sense of more room when we insert our feet.
Brands that tend to run larger than normal
In our experience , there are some brands that stand out because their most iconic styles tend to offer a slightly larger size than the label indicates. These include:
Nike : Especially in lines like Air Max or some Dunk editions, the last length is larger than usual. Dunk models are also ideal if you want to add a twist to your look and make it more colorful. This can be very convenient if you're looking for freedom of movement or if you use insoles.

Adidas : Models like the Stan Smith or certain versions of the Gazelle have a loose fit. If you want a tighter fit, the solution is to go one size smaller than you normally wear.

Puma : In its retro-inspired models, like the Speedcat , the toe box offers more room than other brands. This is something many customers appreciate if they can't stand feeling cramped.

New Balance : Classics like the 530 or 9060 tend to have wider lasts, especially in width, making them a perfect choice for wider feet or those looking for extra comfort.

This doesn't mean that all models from these brands are larger, but it's a good idea to pay attention and check the size guide before purchasing , especially if you're buying online.
Tips for choosing the right size when shopping online
Shopping at Newcop's online store is a quick and convenient way to update your sneakers, but choosing the wrong size often means returns. To avoid this, follow these tips:
Measure your foot at the end of the day , when it is slightly more swollen, to ensure you choose the correct size.
Always check the size guide for the brand and model you're interested in, as there may be differences even within the same brand.
Read other buyers' reviews , as many indicate whether the model is larger or smaller than expected.
Consider your intended use . If they're for sports or everyday wear, a little looseness can be beneficial; if they're for dress, they should fit snugly without being too tight.
Think back to your previous experiences . If you usually have to order a half size smaller with that brand, you'll probably have to do the same with that model.
