Brooks Shoe Size Chart

Brooks's own published size chart, covering a 23cm to 34cm foot, with 4 real width fittings rather than length alone, and no children's range at all; Brooks's own guidance is to size younger runners on the adult scale. Every figure below is keyed to a measured foot length rather than converted from another size number. Open the calculator with Brooks selected to read it against all 35 brands at once.

Does Brooks run small?

For women's sizes, yes. By its own size chart, Brooks is in line with most brands in men's sizes and runs about half a size small in women's sizes. A 24 cm foot is a women's US 7 in 16 of 34 other brands' charts, and a US 7.5 in Brooks. Charts show how a brand means its sizes to fit, not how any one shoe feels, so read Brooks's own fit advice below as well.

How this is worked out: every foot length from 25 to 29 cm (men's) and 22.5 to 26 cm (women's), in 1 mm steps, is read against Brooks's chart and the other 34 brands' charts the way the calculator reads them, rounding up between sizes. The answer is the average gap between Brooks's size and the size the other brands give most often. See the methodology.

Brooks width chart

Brooks publishes 4 men's and 4 women's width fittings. The standard fitting is D in men's and B in women's, so a D is the standard men's fitting but a wider women's one. Check which chart a letter belongs to before carrying it across.

Women's fittings

Not every model is made in every fitting. Enter a forefoot width in the calculator and it returns Brooks' own fitting for your foot. The width chart compares fittings across brands, and the wide-feet guide shows how to tell whether your foot is wide.

How to measure for Brooks

Measure heel-to-toe standing, using the longer foot. Measure in the afternoon or after a run, when feet are at their largest.

Brooks fit guidance

Brooks and most running specialists recommend going about a half size up from your everyday shoe size, to leave room for the foot to swell and move forward during a run. IMPORTANT: Brooks does not manufacture children's shoes. Their own guidance is that younger runners should use adult sizing: a big kid's size runs 1:1 with Brooks men's, or add 1.5 for Brooks women's. Most Brooks men's shoes start at a 7, with some spikes and racing shoes down to a 5; women's start at a 5, equivalent to a big kid's 3.5. The range shown here is therefore narrow on purpose. It is the span Brooks can actually fit, not a children's chart. Brooks also notes adult lasts may run wider than a traditional kids' shoe. Brooks runs a full four-fitting width programme on many models: men's B, D (standard), 2E and 4E; women's 2A, B (standard), D and 2E. Note the overlap trap: a D is the standard men's fitting but the WIDE women's fitting. Brooks also advises ordering running shoes half a size to a full size larger than your casual shoes, which is separate from width and should not be used to compensate for a narrow fit.
