One heel, two forms
DuoHeels started with a simple frustration: carrying flats in your bag for the walk home after wearing heels all night. So we engineered a convertible heel — a locking toggle mechanism that flips between a poised block heel and a flat sandal in one motion, with no wobble in either position.
Every pair is engineered and tested for real wear: an over-centre lock rated to 2-3x bodyweight, a flexible sole plate with a living-hinge flex band, and a symmetric double-lock geometry that's equally secure heel-up or heel-down.
DuoHeels is a product of Infavy Interactive Private Limited, based in New Delhi, India.
