Stack describes height; drop is the difference between heel and forefoot. These dimensions are not quality scores. Weights from different sizes are not precise comparisons of equivalent samples.

What to consider

This category describes support features in the construction. It does not diagnose your gait, establish a need for correction or promise injury prevention.

Try the size with your usual socks, checking toe room and secure hold. Foam names, plates and prices cannot replace this assessment. This page does not prescribe footwear or attribute injury prevention to the model.

Independent measurements

No compatible measurements are recorded for this model. Missing data is not a low score or zero.

These measurements do not replace the product specifications above. They describe a laboratory sample and protocol, not Darwin tests or a guarantee of individual feel.

Sources and limitations

These details combine compiled specifications. Each source is identified; a laboratory, manufacturer and retailer provide different evidence. Darwin did not perform the tests.
