Shoe sizing isn’t universal—each brand uses different lasts, materials, and design styles that can cause a half-size or full-size difference between brands. For example:
- Nike tends to run small, so you might need a half-size larger.
- Converse runs large, so sizing down is common.
- Brooks and New Balance often have wider fits, great for broader feet.
If you’re shopping for a new pair of shoes and are unsure how the fit compares, use our Shoe Size Converter below to find your ideal match. Brands include running shoes, basketball shoes, casual footwear and formal she brands to help you get a great fit when you are switching from one brand to another and want a perfect fit.

Common Fit Issues and How to Solve Them
- Wide feet? Choose brands like New Balance, Brooks, or Keen, which offer wider options.
- Narrow feet? Adidas and Puma tend to run narrower.
- Need extra arch support? Look for orthotic-friendly brands like HOKA or ASICS.
