💡 Korean Foot Characteristics

Koreans tend to have slightly wider feet and higher insteps compared to Westerners. When buying foreign brands (especially Nike), sizing up by half (+5mm) is a common tip if the width is standard (D/B). If width options like 2E (New Balance) are available, choosing 2E with your true size may provide a better fit.

Why Do My Shoes Hurt Even When the Length is Right?

Most people only focus on length when buying shoes. However, half of the comfort equation is Shoe Width. Even if length-wise the shoe fits, a narrow toe box can compress your toes leading to bunions, while a shoe too wide can cause blisters due to friction.

Understanding Foot Shapes

Foot shapes vary globally. Western brands like Nike often design for a narrower 'Standard (D)' foot shape. However, many people, especially in Asia or those with flat feet, have wider forefeet. This mismatch is why sizing up is often necessary.

Breaking Down Width Codes

One letter can change everything. Here is what you need to know:

  • B (Narrow): Standard for Women, very narrow for Men.
  • D (Standard): Standard for Men, Wide for Women. Most Nike and Jordan sneakers are D width.
  • 2E / EE (Wide): Ideal for those with wider feet. Often found in New Balance and Asics specialized models.
  • 4E / EEEE (Extra Wide): For very wide feet or high insteps.

Brand Specific Advice

  • Nike: Runs narrow (D). If you have wide feet, go up half a size (+5mm).
  • New Balance: The king of width options. Look for 2E or 4E models like the 990 or 574 series to get a perfect fit without oversizing length.
  • Adidas: Slightly wider than Nike, but still standard. Sizing varies by model.
  • Converse: Chuck Taylors are long and narrow. Size up if you have a wide forefoot to avoid pinching.

Do I Have Wide Feet?

Stand on a piece of paper and trace the widest part of your foot. If you wear a US Men's 8 (260mm) and your width exceeds 100mm (3.9 inches), you likely have wide feet. In this case, prioritize models offering 2E width options for better foot health.
