Are you trying to figure out “Do SAS Shoes Run the Same as Nike in Size?” You’re not alone — many shoppers struggle to find the perfect fit between these two popular brands. Based on years of footwear expertise and hands-on experience with both SAS and Nike shoes, we’ve found that SAS shoes usually run a bit larger, while Nike designs tend to fit snugly. This difference often leaves wearers wondering which size to choose for optimal comfort.
In this guide, we’ll walk you through detailed size comparisons, expert tips, and real-world insights to help you confidently pick the right pair that fits like a glove.
Do SAS Shoes Run the Same as Nike in Size?
SAS shoes are generally true to size, meaning if you wear a size 9, you can stick with a size 9 in SAS. However, based on our experience, SAS shoes tend to be wider and more spacious. This may make them feel looser when compared to Nike, which are known for their snug fit. Nike shoes, especially around the midfoot and heel, often feel tighter, giving a more secure fit.
What to Do If You Get the Wrong Size?
If you end up with the wrong size in SAS or Nike shoes, don’t panic. Both brands have return policies to make exchanges easier.
- SAS Return Policy: SAS offers a 30-day return policy, provided the shoes are in new condition, with original tags and packaging.
- Nike Return Policy: Nike allows returns on unworn, unwashed shoes within 60 days, no questions asked. Plus, if you’re a Nike member, you get free returns.

Understanding SAS Shoe Sizes
We’re fans of SAS shoes for their supreme comfort, which comes down to their sizing. SAS shoes generally run true to size, making it simple to buy the correct size. If you usually wear a size 8, stick with a size 8 in SAS. But there’s a little more to it. SAS shoes often have extra room, especially in width.

Understanding the Fit Philosophy: SAS vs. Nike
When comparing SAS and Nike, the difference begins with design philosophy. SAS shoes are handcrafted in the USA and focus on comfort, support, and orthopedic balance, appealing to those who prioritize all-day wear. On the other hand, Nike shoes are built around athletic performance, offering a snug, dynamic fit designed to enhance agility and movement.
This distinction explains why SAS shoes often feel roomier and softer, while Nike models tend to hug the foot more tightly — perfect for sports and active lifestyles.
How to Choose the Right Size Between SAS and Nike
If you’re switching from Nike to SAS or vice versa, here’s what you should know:
- SAS shoes typically run about half a size larger than Nike shoes.
- For most wearers, going half a size down in SAS provides a closer match to your Nike fit.
- Always check the brand-specific size chart — SAS provides both length and width options, while Nike focuses more on athletic sizing.
Trying shoes on in-store or ordering from retailers with easy exchanges is a smart move, ensuring you find your ideal balance of comfort and support.
Tips to Ensure a Perfect Fit Every Time
Even with accurate charts, sizing can vary slightly across styles. Here’s how to get the best fit:
- Measure your feet in the evening, when they’re at their largest.
- Wear the same socks you plan to use with your shoes.
- If your toes touch the front in Nike shoes but not in SAS, you may need half a size smaller in SAS.
- Pay attention to the width — SAS shoes often have multiple width options, which can make a huge difference in comfort.
These simple steps can help you make smarter decisions when buying online or in-store, preventing discomfort and returns.
