Vari-Flex® with EVOTM
Videos?
For 25 years, Flex-Foot® has been the foot of choice for prosthetists and amputees alike and with the new Vari-Flex with EVO, the evolution continues.
The Vari-Flex with EVO provides a unique combination of comfort and dynamics, and is designed to make life easier – for everyone.
For prosthetists, the Vari-Flex with EVO is lightweight, easy to assemble and its slender profile makes it easy to cover cosmetically. And for amputees it ensures the highest levels of confidence and security. Offering natural gait with less fatigue and ultimately less strain on the lower back and sound side, it is the ideal foot for any activity.
Vari-Flex with EVO enables amputees to walk more comfortably, better and for longer.
Vari-Flex with EVO Features
Ideal for most activity, Vari-Flex with EVO replicates the functions of the human foot beautifully. Its extra smooth roll-over motion contributes to a more natural, symmetrical gait, which means less fatigue and ultimately less strain on the lower back and sound side of the body.
8 out of 9 amputees who trialed the Vari-Flex with EVO said they preferred it to their previous foot. And 9 out of 10reported a significant and positive differencewhen walking barefoot.
"On a scale of 0-5, I'd give it a 6!"
A big bonus for many people using this foot is the ease with which they can now walk barefoot. Most prosthetic feet are aligned for use with shoes, and removing them usually alters gait significantly. However in trials, users commented on improved stability in all types of situations, particularly when walking without shoes.
Who it is for:
- People with all kinds of lifestyles / activity levels.
- Those who are looking for a smoother roll over and energy-efficient gait.
- People who weigh from 100-365lbs / 44-166kg.
The Technical Stuff
Made of specially layered carbon fiber for strength and functionality, the Vari-Flex with EVO is a lightweight, slender prosthetic that is easy to cover cosmetically. A durable, responsive foot, it has a split toe for enhanced stability. It is available in sizes 22-30cm and with a choice of beige or brown foot covers. A low profile Vari-Flex with EVO is also available for those with longer residual limbs.
More energy, less fatigue.
If you think the Vari-Flex with EVO could be right for you, discuss it as an option with your prosthetist.

The Groundbreaking EVOTM Feature
EVO stands for Energy Vector Optimization. This unique Flex-Foot feature controls how the scale and direction of ground reaction forces are transferred to the prosthetic foot. In doing so, it makes the foot more ground-compliant and helps improve ankle control.

The EVO (Energy Vector Optimization) feature is generated by controlling how the ground reaction force is transferred to the prosthetic foot. Each step is optimized through the magnitude, placement and direction of forces for maximum efficiency. EVO enables the amputee to develop the most natural gait progression possible which reduces fatigue and puts less pressure on the sound side.
The EVO Feature Provides:
- Fluent roll-over which mimics natural gait progression
- Reduced fatigue
- Effortless control of the ankle during stance phase
- Less pressure on the sound side
- Less pressure on the lower back
