The shoes and the sensor come with an app which is free of charge. The users can adjust plenty of settings through it, such as how far away from objects they need to be before they get alerted.
If you wonder what happens when the weather is rainy or snowing, the creators thought of it and made the sensor water-resistant. If users opt to use the intelligent mode, the sensor would get deactivated whenever they are seated and would again activate when it senses movement.
There are several shops around Austria which let users try the shoes on before they buy them.
