01 — The need

When the feet can’t feel, something has to be watching.

19–34%

of people with diabetes develop a foot ulcer in their lifetime. 1

40% → 65%

of healed ulcers return within one year, and within five. 2

30–50%

estimated five-year mortality after a diabetic foot ulcer. 2

~101M

adults live with diabetes in India, about 1 in 9. 3

Watching early works

Ulcers appeared less than a third as often.

A 15-month randomised trial of people with a prior ulcer compared home monitoring for early warning signs with standard care. 4

Standard care29.3%
Monitored at home8.5%

02 — The idea

An insole that pays attention, so the wearer doesn’t have to.

Wear it

An everyday insole, in an everyday shoe.

It watches

Quietly, day after day, for the earliest changes.

Your doctor is told

Linked to your doctor, who hears the moment something needs attention.
