Orthopedic orthosis with strain-adapted zones

TRIactive supports your foot arches in case of flat feet, splay feet and skew feet. As a result, it provides relief of strain-related pain and negative consequences. Thanks to its arrangement of functional cushions with varying densities, it allows different movement patterns.

  • Targeted cushioning and guidance of the feet
  • Supports the foot arches during sports and leisure activities
  • Jigsaw puzzle serrations for strain-specific functional zones ensure smooth transitions

More than the sum of its parts

Flat feet, splay feet or skew feet can become unbearable and cause unpleasant negative consequences: irritation of the Achilles tendon, knee pain and back pain are frequently caused by the feet. The specially developed TRIactive can provide relief here. TRIactive provides targeted protection, cushioning and guidance for your feet. This protects the musculoskeletal system, thereby reducing knee and back pain. The “jigsaw puzzle" appearance of TRIactive is produced by the arrangement of functional cushions with varying densities coordinated for different movement patterns.

Specialist advice

TRIactive is only available from medical retailers. The orthotist will measure your feet and then use the orthotic blank to prepare a customized foot orthosis specially for you. The foot orthosis is available in the "run," "play," "walk," and "golf" versions. This makes it suitable for running, indoor sports and ball sports, walking, hiking and golf as well as for people who spend long periods standing in their everyday lives. TRIactive fits in sports shoes, hiking shoes and comfort shoes: in fact, it will fit in any footwear with a removable insole.


  • Premium soft foam foot orthosis made from high-quality EVA with pad
  • With sport-specific guidance, support and cushioning zones arranged (vertically) adjacent to one another (no "sandwich" construction)
  • Patented, three-dimensional, non-irritant connections between the material zones – PowerWave Technology

Material zones

Cushioning zone (25° Shore A):
The soft cushioning zone reduces the pressure and load peaks in the forefoot and metatarsal areas – for the constantly recurrent load pattern of the landing, supporting and pushing off phases involved in walking and running, in order to protect the entire support and locomotor system.

Support zone (35° Shore A):
The support zone provides extensive absorption of the body weight in the metatarsal area and guides the movement on to the forefoot. The moderately rigid material prevents the foot sinking down too far, thus ensuring that valuable energy is not lost. The integral pad supports the natural transverse foot arches and counteracts the high level of pressure under the MTP-joints.

Guidance zone (45° Shore A):
The stable guidance zone offers the heel and the hindfoot a secure grip, thereby optimizing the natural orientation of the foot. The rigid material in the toe area provides a stable surface for accelerating, changing direction and stopping (design: play).

Available in the following designs

  • TRIactive run – standard shoe shape and comfort shoe shape*
  • TRIactive play – standard shoe shape only
  • TRIactive walk – comfort shoe shape* only
  • TRIactive golf – standard shoe shape only

* Comfort shoe shape has a wider forefoot area and flatter arch supports


  • Suitable for running, indoor and ball sports, walking and hiking and when spending long periods standing


  • fundamentally depends on the load
  • We recommend that the functional properties should be checked after a maximum of 6 months

Cleaning instructions

  • Wipe the surfaces using a mild cleanser and a sponge (except leather top covers)
  • Not machine-washable
  • Do not expose to direct heat (heater, direct sunlight)

Modification instructions - Specially for medical retailers

  • Must be ground (lateral foot orthosis shape and foot orthosis strength)! – easy to grind (grinding belt, grain 40-100, polishing brush on the blade disk)
  • Good for bonding (standard workshop adhesives)
  • Partial thermoplastic molding possible (hot air blower, up to 120°C (248°F), 20-30 sec.)
  • A top cover, e.g. microfiber, is recommended for the mechanical protection of the EVA material
