Trias+ Foot


Trias+The Trias+ foot was modeled after the anatomical function of the human foot. It was engineered to ensure effortless, unified function. The design combines dual spring elements in the heel and forefoot. It is a base spring that ties these two elements together...resulting in an excellent heel response and easy rollover for superior gait characteristics.

The Trias+ is ideal for patients who meet K3 activity criteria. This lightweight walking foot delivers a flowing response that complements the user’s stride. The durable carbon fiber construction ensures solid dependability for patients who weigh up to 275 pounds.
