The square-toe Mary Jane pumps list white, red and black options, a faux-leather upper, ankle strap, EVA outsole and 9 cm heel. The size chart includes foot length rather than only an international conversion. Use that length first, then treat toe width, strap reach and the heel as three separate questions.

Work from your measured foot length

Measure both feet while standing and use the longer result. The listing maps size 35 to 22.34 cm, 37 to 23.66 cm and 40 to 25.64 cm. As a hypothetical example, a longer foot measuring 23.6 cm falls just under the listed 23.66 cm row for size 37; that is a starting row to verify, not a fit guarantee. Ask whether these numbers are recommended foot lengths or interior shoe lengths and whether extra toe clearance is already allowed.

Check the space the chart does not measure

A square toe describes shape, not the interior forefoot width. Compare your widest forefoot with a pair of pumps you own and request the interior width for the proposed size. Ask for the ankle strap’s usable adjustment range, buckle position and whether the strap crosses your instep. The product text calls it an ankle strap but gives no range or on-foot fit test.

Treat the 9 cm heel as its own decision

The listed heel height is 9 cm, but there is no forefoot platform measurement or tested stability result. Do not subtract an imagined platform height or infer a comfortable pitch. Compare the heel position and height with shoes you already wear and request a side profile photo. Confirm outsole grip and return fit terms from the live product page before purchase; this article cannot promise comfort.
