Scan your feet with your iPhone. Pick a style. A pair is made to your scan.
Not a 12 or a 13 or a wide. Your foot, to the millimetre.
The footbed is the shape of your foot from the first day: your arch, your heel, your toes.
Your scan stays with you. Every style you pick later is made to it.

Two wide straps. The everyday sandal.

A slim toe strap and a heel strap.

A closed slip-on, shaped to your toes.

Laced, cushioned, a little lift at the heel.
Walk your phone round each foot. The app shows you when it has enough.
A style, a strap, a sole. Snug, standard or roomy.
You see your pair before it's made. Then it's made and sent to you.
A shoe size is a step of 8 mm. Your scan is good to 1 mm.
Leave an email. You'll hear when the app is ready to try and when the first pairs are made. Nothing else.
Needs an iPhone 12 Pro or later. Other phones come later.
