How to Use the Brand Shoe Size Converter
Step-by-Step Guide
- Select Your Brand: Choose the brand you're shopping for (Nike, Adidas, New Balance, Converse, Puma, Skechers, Vans, etc.). Each brand may have slightly different sizing, so selecting the correct brand ensures the most accurate conversion.
- Select Your Gender: Choose whether you're converting men's, women's, or kids' shoe sizes. Brand sizing can differ between genders, so this selection is crucial for accuracy.
- Select Your Size System: Choose the size system you know your size in (US, UK, EU, or CM). This is your starting point for the conversion.
- Enter Your Shoe Size: Enter your current shoe size. The converter will use the brand's official size chart to provide accurate conversions to other sizing systems.
- View Brand-Specific Conversions: The converter displays your equivalent size in other systems based on the selected brand's official sizing data, helping you shop with confidence across different regions and retailers.
Why Brand-Specific Sizing Matters
Nike Sizing Characteristics:
Nike shoes often run slightly narrow and may fit smaller than other brands. Many customers find they need to size up 0.5 sizes in Nike compared to other athletic brands.
Adidas Sizing Characteristics:
Adidas typically uses true-to-size EU sizing as their base. Their US and UK conversions are generally consistent, but some models may run slightly large or small depending on the shoe type.
New Balance Sizing Characteristics:
New Balance is known for offering wider width options. Their standard width may feel slightly wider than other brands, which can affect size perception. They also tend to run true to size.
💡 Pro Tip: Even within the same brand, different shoe models (running, basketball, lifestyle) may have slightly different fits. Always check customer reviews for specific models when available, and consider trying on shoes when possible.
