Choosing a running shoe online starts with knowing exactly which model you are looking at. A familiar size label is a useful starting point, but it is not a promise of the same fit across every shoe.
1. Check the full model name
Keep version numbers and suffixes together. A standard model, a Pro version and an SL version are separate products; their construction and size references should be checked separately.
2. Keep foot length separate from insole length
Your foot measurement, the length of a removable insole and the number printed on a shoe label are different pieces of information. Do not substitute one for another without the exact model chart explaining how it is used.
3. Look for the model-specific chart
Use the chart supplied for that model and market, and read whether the measurements describe feet or shoes. Avoid transferring a conversion from an unrelated brand.
Our measurement guide explains how to prepare both foot measurements. Verified model charts will be added before our preview products become available to order.
