Converse: Manufacturer advice
There is no verified brand-wide fit offset or reproducible wearer distribution in this dataset. Size labels and measured foot length are different quantities. A chart does not establish the fit of every model.
Chuck Taylor All Star Canvas
For the A15958F canvas low top, Converse advises half a size below your usual size because this style runs large. Use the Chuck Taylor All Star / Chuck 70 chart below; this advice does not cover every Converse model. The chart has separate US men’s and women’s labels. At 245 mm it publishes two rows, so the measurement alone does not select one unique size.
