Tested by women
Data-driven design
Our first shoe, the Alma, was shaped by the feedback of an all-female run study we conducted prior to launch. Over the course of 6 weeks and 22 runs, 60 women (of all ages) tried and tested different prototypes. The data we collected from each survey helped us improve the shoe for comfort and performance—and it inspired us to release 3 models to accommodate different types of running workouts.
Our mission in motion
In addition to our all-female run study, Hettas has published a literature review and secured a three-year partnership with a university lab to research the relationship between female physiology and running.
Asking the overlooked questions
The female body undergoes significant changes throughout the lifetime: second puberty, menstruation, pregnancy, peri-menopause, and menopause. Part of our purpose is to research these changes in relation to running, so that women can get answers to questions that have been historically ignored or deemed unimportant.
Lower heel cup
Our lower heel cup reduces rubbing on women's ankle bones and holds the heel in place without putting pressure on the Achilles.
Female-first fit
Our rounded instep creates a snug fit through the middle to match the curvature of a woman’s foot.
VeloPropulsion midsole
Our proprietary midsole technology combines Supercritical foam with a Pebax plate for heel stability and enhanced rebound to keep tired legs going.
Breathable upper
Our lightweight upper made of TPU mesh makes for a stretchy toe box to accommodate the shape of women's toes.
