Determining your correct shoe size might feel straightforward—but if you fall for common myths or shortcuts, you could end up with ill-fitting shoes that lead to discomfort or worse. Here are a few tricks you should avoid when judging your shoe size:
1. Avoid Using a Foot Tracing
You might think tracing your foot on paper gives you accurate measurements—but that tracing can be as inaccurate as your posture when you draw. Besides, it doesn’t account for fluctuations in foot volume during the day. Rely on proper measurement methods, not DIY tracings.
2. Don’t Compare Your Foot to Your Forearm
For some reason, people sometimes think their forearm gives them a shortcut to shoe size—but you shouldn’t compare your foot to your forearm. They’re completely different proportions, so this comparison is just misleading.
3. Skip the Thick Socks Test
Putting on thick socks and trying to size up “just in case”—that’s a big no-no. It might feel like you’re creating comfort, but it’s obscuring the true fit. Always size your shoes with the actual socks you’ll wear day-to-day, not padded duplicates.
At a Glance: Tricks to Avoid
| Trick to Avoid | Why It Misses the Mark |

By steering clear of these shortcuts, you ensure you’re measuring your shoe size accurately—and setting yourself up for proper fit, better support, and healthier feet.
