Find your usual US women’s size in the first column, then read across for the men’s equivalent, UK size, EU size, and foot length. Most styles fit true to size; the slip-in heel adds no extra length.

• Foot length is measured heel to longest toe
• US men’s sizing is shown for reference

Men’s styles run on the same last as the women’s range, offset by 1.5 sizes. Pick your normal US men’s size and check the foot length against a traced outline before ordering.

• Unisex styles follow this table
• The slip-in collar does not change the length

Width is measured straight across the ball of the foot, not around it. Wide (2E) runs about 3 mm wider than standard at the same length. Extra Wide (4E) adds further width and volume through the forefoot in select styles — if standard is only just too tight, start with 2E before moving to 4E.

• Widths apply to both women’s and men’s US sizes
• High arches and high insteps fit best in 4E

Built for ages 8 to 12, big kids’ sizes step up half a size at a time from a 22 cm foot. Measure both feet and use the longer one — children’s feet rarely match exactly.

• Ages 8–12 years, approximate
• Leave 8–10 mm of growing room

Sizes 7C to 3Y cover roughly ages 4 to 8. Little kids’ styles keep a fixed insole, so check the foot length rather than guessing from age or from the previous pair.

• Insole is fixed in little kids’ styles
• Ages 4–8 years, approximate

Socks are sized by the shoe size you wear, not by foot length. Only two sizes are made, so the ranges overlap at women’s 10 and men’s 8 — choose Medium for a closer fit, Large for a roomier one.

• Ranges refer to US shoe size
• No sock sizing for US men above 12

Measure late in the day, when feet are at their largest, and wear the socks you plan to pair with the shoes. Two minutes with a sheet of paper is more reliable than any size you remember from another brand.

A few rules of thumb that resolve most exchanges before they happen.

• Between two sizes? Go up

  The hands-free heel cage works best with a little clearance at the toe. Half a size up still holds the foot securely.

• Wide feet start at 2E

  If standard widths usually pinch across the ball, begin with Wide (2E). High arches and high insteps do better in 4E.

• Measure in the afternoon

  Feet swell through the day. A morning measurement can read up to half a size short of your evening size.

• Knit gives, leather holds

  Knit uppers relax slightly with wear. Structured leather and waterproof styles keep their shape, so size those true.

• Socks change the fit

  Thin no-show socks sit closer than cushioned crew socks. Measure with the pair you will actually wear.

• Kids grow fast

  Leave 8 to 10 mm of room at the toe. That is roughly a thumb’s width between the longest toe and the front of the shoe.
