From the Men > Footwear tab: the 'Length of foot' table (inches and cm) plus the 'International Sizing' table (US, UK, EUR, JAPAN) printed further down the same tab. The page says the chart measurements are foot measurements. The international table stops at US 14, so UK, EU and JP are empty for US 15. Tall-boot, half-chap and slipper tables on the same tab are not included.

From the Women > Footwear tab: the 'Length of Foot' table (inches and cm) plus the tab's 'International Sizing' table (US, UK, EUR, JAPAN). The page says the chart measurements are foot measurements. The brand prints whole-centimetre foot lengths here (e.g. 23 cm for both US 6 and 6.5). The slipper/sock table on the same tab prints slightly different inch values; the main footwear table is used.

From the Kids > Footwear tab: the 'Length of Foot' table plus the tab's 'International Sizing' table. US 8-13.5 are little-kid sizes and 1-6 big-kid sizes. The brand leaves the Japan size empty for US 9.5, 10.5 and 12.5. The tab's intro sentence calls the chart values body measurements, but the rows are labelled 'Length of Foot'.

Convert your Ariat size to another brand
What we could not verify
- Ariat Insider loyalty page (https://www.ariat.com/insider) and the retailer locator (https://www.ariat.com/retailers) redirected to the homepage when opened from Japan, so neither is listed; storeLocator is the Ariat-owned stores page. The site also lists Finland in its regional sites (12-site limit).
- No shopping app linked from the site.
- The men's international conversion (UK, EU, Japan) on the size chart page stops at US 14, so US 15 has only US size and foot length.
- Width letters come from an Ariat buying guide, not from the size chart page; check each product page for the widths it is made in.
Questions
Which length does Ariat's size chart list?
Ariat's charts give these lengths — CM: measured foot length · JP: size in cm. A measured foot length and a size in cm are about 8 mm apart for the same size, so compare your own foot length only with a column on the same scale.
Does the official chart tell me how a Ariat shoe will fit?
Only in part. The chart gives the length each size is meant for; how a particular model fits also depends on its last, width and materials, which the chart does not show. Ariat itself advises: If you are on the borderline between two sizes, order the smaller size for a tighter fit or the larger size for a looser fit. Measure your foot with Ariat's printable footwear sizing guide; the chart values are foot measurements.
When should I not compare Ariat sizes with another brand?
When the two charts list different lengths. A measured foot length and a size in cm are about 8 mm apart, and the length of a foot is not the inside length of a shoe, so such a match can be half a size or more off. The converter matches only lengths on the same scale and lists the other brands separately.
When was Ariat's chart last checked?
On 2026-10-24, against Ariat's official size guide linked under each chart. The date changes only when the chart is checked again against the official page or its numbers change, not when this page's layout or wording changes.
