Does Clarks run true to size?

Clarks women's shoes, by its own chart

Chart runs short: half a size up

By its own size chart, Clarks builds each size for a foot about 0.4 cm shorter than the median of 14 other brands' charts. On length alone that points you half a size up, and sizing up is the safer mistake.

Convert your size to Clarks

If you wear this at another brand, buy this at Clarks

US women's sizes. Each cell reads the other brand's own chart, then finds the Clarks size built for the same foot (or the same label, when one chart has no foot lengths).
You wear	Size 7 there	Size 8 there	Size 9 there
Nike	Clarks 7½	Clarks 9	Clarks 10
adidas	Clarks 7½	Clarks 8½	Clarks 9½
HOKA	Clarks 7	Clarks 8	Clarks 9
Brooks	Clarks 7	Clarks 8	Clarks 9
ASICS	Clarks 7½	Clarks 9	Clarks 10
New Balance	Clarks 7½	Clarks 9	Clarks 10
On	Clarks 7½	Clarks 9	Clarks 10
Saucony	Clarks 7	Clarks 8½	Clarks 9½

Every size, not just these three: follow a brand name for the full Clarks table.

Size by size: Clarks against the other charts

The foot length Clarks 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	Clarks builds it for	Median brand	Difference
6	22.6 cm	23 cm (14 brands)	-0.40 cm
6.5	23.1 cm	23.5 cm (13 brands)	-0.40 cm
7	23.6 cm	24 cm (14 brands)	-0.40 cm
7.5	23.9 cm	24.2 cm (13 brands)	-0.30 cm
8	24.1 cm	24.55 cm (14 brands)	-0.45 cm
8.5	24.6 cm	25 cm (12 brands)	-0.40 cm
9	25.1 cm	25.5 cm (14 brands)	-0.40 cm
9.5	25.4 cm	26 cm (12 brands)	-0.60 cm
10	25.9 cm	26.5 cm (14 brands)	-0.60 cm

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.
