On Running size chart & fit
On Running sizing depends on the product and regional chart. Compare measurements before choosing a label.
Sizing philosophy
A brand name does not define one universal fit. Different collections and product categories can use different shapes, widths and size charts.
How On Running shoes fit
Fit varies by model, version, material, width and market. Use the current product measurements and fit instructions rather than a brand-wide size adjustment.
Width & last
Width availability varies by model, size and market. Check the product’s width selector; increasing length is not a reliable substitute for the correct width.
Choosing your size
Use On Running’s current product chart. A generic table is not a verified On Running chart; conversions and fit can differ by model and market.
