Taleo
The Taleo feels more natural and comfortable. The prosthetic foot features a smooth rollover, and its efficient energy return supports a dynamic gait. In doing so, it adapts flexibly to the individual way you walk and various surfaces and inclines. The Taleo is resistant to fresh, salt and chlorinated water. Additional water runoff channels on the adapter and openings in the sole of the foot prevent water from collecting in your prosthesis and interfering with your activities.
