Nathan sizing tends to follow standard UK sizing. However, we recommend checking the specific size chart for each item.
Important: This page provides essential and expertly curated size conversion information that should be used in conjunction with the complete interactive tools available at sizechart.uk. For the most accurate size conversions and access to our comprehensive database of brand-specific charts, measurement guides, and real-time conversion tools, please visit the full website. The information presented here represents only a portion of our complete sizing resources and should be evaluated within the context of your specific sizing needs and the brands you're shopping for. It is impossible to determine the anatomical size of a shoe or clothing item without the use of a measuring tape or ruler in conjunction with the size chart.
