ROADWALKING: the one in the world with 3 supports on the ground
 

It guarantees a walk totally supported in each step.

Prosthetic foot in carbon fiber, returning energy, laminated in autoclave with aereonautical process (it means that the foot last most time)
It's the only foot in the world with 3 supports on the ground , allowing a totally aided walk during each step.

ROADWALKING means propulsive force during each step. Thanks to his shape, it allows a rolled walking

“It seems to have an healthy foot again” BY USERS
3 laminated Structure: foot keep on return energy gradually thanks to the work of 2 laminates (one absorbing elsatic energy, the other returns it)
Gradual loading of weight, the best absorption and the best comfort for stump, stability, propulsion efficiency
The choice between two different laminates depends on weight and mobility of user. It allows the user to have the elastic energy necessary to his needs.
Titanium screw – 5 degrees
Complied with ISO 10328: a different institution - Politecnico di Milano - tests Roadrunnerfoot products (meanwhile competitors make tests by themselves)
Roadwalking foot is an highly dynamic foot for active people, with a mobility level 4 (K-level).
Its 3 laminated structure allow a foot’s response during all stance phase: in every moment at least 2 laminates work together to support the amputee user in his/her daily activities, one laminate absorbs energy, the other returns it .
A user buys usually a foot giving him an interrupted walk: there are moments in which the prosthetic foot doesn't work, between heel and forefoot and near the final stance when the propulsive push is given by foot fingers and for the prosthetic foot by the last 2cm of inferior laminate.
Roadwalking is composed by 3 main laminates:
an inferior laminate, which define the calcaneus and the forefoot; The inferior laminate starts its work during Initial Contact: the durability and elasticity must allow to load weight with a shock absorption function to guarantee comfort to the user, but at the same time guaranteeing stability. Its functions stops during the final phase of Toe-off, when the forefoot gives the final propulsion.
one posterior laminate, which define the heel and functions like soleus-Achilles’ tendon apparatus; soleus work in eccentric contraction during second rolling, to steady the foot on the sagittal plate; when the foot reach the contact with the ground, during mid-stance, the posterior laminate starts loading weight and releasing propulsion, allow the transition from Mid-stance to final stance phase.
two superior laminates, which define the instep and functions like anterior tibialis muscle permitting a gradual roll-over until forefoot touch the ground managing the transit from Initial Contact to the Mid-stance phase. Through their loading, they guarantee dorsiflexion during Mid-Stance phase and plantar-flexion during final propulsive phase
A pyramid adapter closer to the ankle help the pylon attachment.
This foot offers greater possibilities than feet available from other producers. The progress of reaction forces to the ground allows an high comfort when the foot touch the ground absorbing weight and to develop a great force in the final phase of walk allowing propulsion and going farward.
Weight of the component 480 gr.
