The Hettas chart below is verified against the brand's official sizing. Numbers are foot-length measurements for each US women's size, not garment measurements.
Hettas fit — the short version
Built on a women-specific last: snug, narrow heel with a roomy, triangular toebox that lets toes splay. The brand and most reviewers agree the shoes run about a half size short — order a half size up from your usual Asics women's size. Each pair ships with two insole thicknesses to fine-tune volume.
