Ottobock Meridium (1B1-2): common questions
Can I change shoes with the Ottobock Meridium?
Yes. The foot adjusts automatically to heel heights from 0 to 1.97 in, so flat shoes and shoes with a moderate heel can both be worn.
Is the Ottobock Meridium waterproof?
No. Ottobock states it is not waterproof. The footshell gives splash protection only, so it should not be worn in the shower or pool.
How often does the Meridium need charging?
Ottobock recommends charging overnight for daily use. A vibration signal warns of a low battery, and the foot switches to a safety mode if it runs out.
