We use our own gender-specific lasts to address the anatomical nuances between different types of feet. Length runs true to size. Form hugging heel cup, sculpted mid-foot, and a generous forefoot & toe box.

Standard | Women’s standard width is B in the heel and C in the forefoot (according to Brannock Device®). Patterns and materials in a given model may influence fit. We always recommend trying our footwear on to ensure the best possible fit.

Standard | Medium-High volume feet tend to be wider with higher arches and insteps.
