Brochure for users


  • Who can use the Terion K2 prosthetic foot?

    The Terion K2 is a prosthetic foot for people with low to moderate mobility (MOBIS 1 ‒ 2) who would like to maintain their mobility in everyday life. It supports the user with a high level of safety and adequate dynamic response. Thanks to its low weight, the Terion K2 is very comfortable and offers perceptible wearer comfort for getting around in everyday life, both at home and in the vicinity.

  • In what ways does the Terion K2 differ from conventional prosthetic feet?

    Unlike conventional prosthetic feet like the SACH and Dynamic feet, the Terion K2 features a combination of carbon fibre glass with a foam heel. This enables dampening and comfortable heel characteristics without having to forgo extended forefoot dynamics.

  • Can the Terion K2 prosthetic foot be used as part of an above-knee prosthesis?

    Yes! The Terion K2 is suitable for all amputation levels meeting the structural height requirements. It works with most Ottobock mechanical and microprocessor-controlled knee joints.

  • Is there a Terion K2 matching my size?

    The Terion K2 is available in a range of sizes from 22 up to 30 cm and a body weight up to 175kg/385 lbs. The sizes 22 and 23 cm come with a slim footshell, while the sizes 24 cm and up are delivered with a normal footshell. Each footshell can be ordered in either beige or light brown.

  • Do I need a new prosthesis to use the Terion K2?

    No, the Terion K2 can be integrated into new as well as existing modular prosthesis systems without any problem, provided sufficient structural height is available. The built-in adapter serves to securely connect the prosthetic foot.
