Saucony women's shoes, by its own chart

True to size by its chart

By its own size chart, Saucony is true to size: each size is built for about the same foot length as the median of 14 other brands' charts. Start with your usual size.

Size by size: Saucony against the other charts

The foot length Saucony builds each US women's size for, beside the median of every other brand that publishes one. Half a US size is 0.42 cm.
US women's	Saucony builds it for	Median brand	Difference
6	22.5 cm	23 cm (14 brands)	-0.50 cm
6.5	23 cm	23.5 cm (13 brands)	-0.50 cm
7	23.5 cm	24 cm (14 brands)	-0.50 cm
7.5	24 cm	24.2 cm (13 brands)	-0.20 cm
8	24.5 cm	24.55 cm (14 brands)	-0.05 cm
8.5	25 cm	25 cm (12 brands)	same

9.5	26 cm	26 cm (12 brands)	same
10	26.5 cm	26.5 cm (14 brands)	same

Tinted rows differ by half a size or more. Brands round their foot lengths, often to the half centimetre, so read the average, not a single row.

What a size chart cannot tell you

A chart gives one number per size: the foot length. Width, toe box shape, the heel and how much the upper stretches are on no chart, and they decide whether a shoe feels short. That is why people sometimes say a brand runs small when its chart says it runs long: a narrow toe box can crowd a foot the chart says fits.

If you have wide feet or sit between sizes, take the larger size, or check whether the model comes in a wide fit.

Wearer reports appear on the shoe converter once five people who own both brands have told us what fits. They rank above the charts, because charts describe a shoe and wearers describe a fit. Add a pair you own to help.
