You know that feeling. You’ve spent an hour reading reviews, comparing colorways, and finally settling on a pair of sneakers you’re excited about. They arrive at your doorstep, you tear open the box, slide your foot in, and… something’s off. Maybe your toes are cramped. Maybe your heel is slipping. Maybe there’s just too much room in the toe box. It’s frustrating, and it’s a problem every sneaker buyer faces: sizing inconsistency between brands.

If you’re trying to decide between New Balance and Adidas, you’re not alone. These two giants are among the most popular athletic and lifestyle footwear brands, but they have fundamentally different approaches to how their shoes fit. Understanding these differences can save you from the headache of returns and exchanges, and more importantly, help you find a pair that feels like it was made for your feet. Let’s break down the fit philosophies of New Balance and Adidas in plain, practical terms.

The Core Difference: Volume and Shape

At the heart of the fit comparison is the concept of volume—the overall space inside the shoe. New Balance is widely known for offering a more generous, accommodating fit. Their shoes tend to have a wider toe box, more vertical space (especially in the toe area), and a generally roomier feel throughout the midfoot. This design philosophy stems from their heritage in running and walking shoes, where comfort for long durations is paramount. If you have wider feet, high arches, or simply prefer a little wiggle room, New Balance is often the more forgiving choice.

Adidas, on the other hand, typically embraces a sleeker, more tapered fit. Their shoes often have a narrower profile, especially in the toe box, and a lower volume overall. This is particularly true for their performance lines, like the Ultraboost or Adizero series, which are designed for a snug, sock-like feel that locks the foot in place during athletic activity. Even their lifestyle models, like the Stan Smith or Superstar, tend to have a more streamlined shape. If you have narrow feet or prefer a glove-like, secure fit, Adidas might feel more natural to you.

Length Sizing: The Half-Size Rule

When it comes to length, both brands generally run true to size, but there’s a catch: the way that length interacts with the rest of the shoe. In New Balance, the length is often accompanied by that extra width, meaning a size 10 in New Balance might feel like a size 10.5 in a narrower brand. Many experienced buyers recommend going half a size down in New Balance compared to your regular sneaker size, especially if you have narrow feet or are buying a model known for being particularly roomy, like the 990 series.

Adidas, conversely, often requires going half a size up from your usual size. This is especially true for performance models with a tight, knitted upper, like the Ultraboost. The snug fit can make the shoe feel shorter than it actually is, even though the length is technically correct. A good rule of thumb is to try on your standard size first, but be prepared to adjust. For Adidas, if your toes feel like they’re kissing the front of the shoe, a half-size up is usually the fix. For New Balance, if you feel excessive space around your toes, a half-size down might be the sweet spot.

Width Options: A Major Differentiator

This is where New Balance truly shines for many buyers. The brand has a long-standing commitment to offering multiple width options across many of their models. You can often find New Balance shoes in narrow (B), standard (D), wide (2E), and extra-wide (4E) sizes. This is a game-changer for people with non-standard foot widths. If you’ve ever struggled with shoes that pinch your pinky toe or feel like your foot is spilling over the edge, New Balance is likely your best bet.

Adidas, in contrast, rarely offers width options outside of standard (D). Their sizing is more uniform, relying on the stretch of the upper material (like Primeknit) to accommodate different foot shapes. While this works well for many, it can be a limitation if you have particularly wide feet. The lack of width options means you’re essentially stuck with the standard fit, which can feel restrictive if your feet are on the wider side.

Model-by-Model Breakdown: Real-World Examples

Not all shoes from either brand fit the same way. Some models have distinct characteristics that can throw off your expectations. Here’s a quick guide to common models:

New Balance 990 (v5, v6): These are the classic “dad shoe” icons. They run true to size but are very roomy. If you have narrow feet, go half a size down or consider a narrow width. They have a generous toe box and excellent arch support.
New Balance 574: A lifestyle staple. They fit slightly snugger than the 990 series, especially in the toe box. True to size for most, but if you’re between sizes, go up half a size.
New Balance Fresh Foam (e.g., 1080, More): These running shoes are designed for comfort. They run true to size but have a plush, padded feel. The toe box is wide but not overly so. If you have wide feet, definitely go for the wide option.
Adidas Ultraboost: The quintessential performance sneaker. They fit snug, especially in the midfoot. Go half a size up from your regular size, unless you have very narrow feet. The Primeknit upper stretches, but the overall fit is tight.
Adidas Stan Smith / Superstar: These classic lifestyle shoes have a low, flat profile. They run true to size but can feel narrow. If you have wider feet, go half a size up. They have minimal cushioning, so the fit is more about snugness than comfort.
Adidas NMD: Similar to the Ultraboost in fit—snug and sock-like. Go half a size up for a comfortable fit. The toe box is particularly narrow.

Practical Tips for Buying Online

Since you can’t try on shoes in a store, here’s a step-by-step approach to nailing the fit:

Measure your feet at home: Trace your foot on a piece of paper, measure from heel to longest toe, and compare that measurement to the brand’s size chart. This is more reliable than shoe size memory.
Consider your socks: If you plan to wear thick athletic socks, account for that. For New Balance, thick socks might fill out the extra space. For Adidas, they might make the shoe feel too tight.
Read reviews for your specific model: Fit can vary dramatically between models within the same brand. Look for phrases like “runs large” or “runs narrow” in recent reviews.
Buy from a retailer with free returns: This is your safety net. Order two sizes (your regular and a half-size up or down) and return the one that doesn’t fit. It’s a small hassle for a perfect fit.

Final Recommendations

So, which brand should you choose? It depends on your foot shape and preferences. If you have wide feet, high arches, or simply value a roomy, relaxed fit, New Balance is almost certainly the better choice. Their width options and generous toe boxes make them incredibly comfortable for all-day wear, especially for walking or standing. If you have narrow feet or prefer a performance-oriented, locked-in feel, Adidas will likely feel more natural. Their sleek, tapered designs are perfect for running, gym workouts, or a more streamlined look.

My personal advice: Don’t assume your size in one brand translates to the other. Start by measuring your foot length and width, then use that data to guide your choice. And when in doubt, lean toward the half-size adjustment—down for New Balance, up for Adidas—and always check the return policy. Your feet will thank you.
