Elan is a microprocessor foot that mimics natural muscle resistance and ankle motion by adapting hydraulic resistance levels to optimise stability when standing and walking, on slopes and uneven terrain. This encourages more symmetrical limb loading, faster walking speed and reduced compensatory movements. The ankle pivot point is optimally positioned close to the natural weight line for a more natural response through the gait cycle.

The result is smoother, safer and more natural walking, helping to preserve the body for the long term.

Key Features

  • Microprocessor controlled self-aligning plantarflexion and dorsiflexion
  • Standing support mode increases resistance when stationary to help improve balance, stability, reduce effort and encourage a more natural posture
  • Variable response to speed changes
  • Increased plantarflexion resistance allows for more energy storage and return when walking quickly or up slopes
  • Ankle remains dorsiflexed during swing phase to increase toe clearance and reduce risk of trips and falls
  • Batteries contained within the ankle
  • Increased dorsiflexion resistance provides a brake when walking down slopes for improved safety and stability
  • Sandal Toe Foot Shell

Key Benefits

Standing Support Mode

When no movement is sensed, the hydraulics stiffen to assist with a natural standing posture, providing equal socket pressures.

Integrated Micro Connector

The refreshed design incorporates an integrated charging connector with a new LED battery power indicator.

Simplified Clinician Setup

The new software interface has been simplified and refined so that it is now easier than ever for clinicians to set up Elan.

Even Longer Battery Life

The battery life is now even longer with up to two days usage between charges and a low power mode.

Why Elan is Different

Ramp Brake

New Elan Ramp Brake

On walking downhill, lower plantarflexion resistance allows the foot to fully contact the slope sooner for improved safety and security. At the same time, increased dorsiflexion resistance provides a braking effect stabilising the user for a safer, more controlled descent.

Ramp Assist / Fast Walk

New Elan Ramp Assist

When walking quickly or up slopes, the plantarflexion resistance increases allowing for more optimal energy storage and return. Combined with a softer dorsiflexion resistance, this aids forward momentum, body position and minimises the effort required to walk fast or uphill.

Standing Support

New Elan Standing Support

Standing for longer periods has also just got easier. A network of sensors detect the user is stationary, increasing resistance to help improve balance, stability, reduce effort and encourage a more natural posture.

Swing Clearance

New Elan Swing Clearance

During swing phase, the ankle remains in a dorsiflexed position increasing toe clearance on every step and reducing the risk of stumbles or falls.

Scientifically Proven


Clinical Compendium

Clinical Compendium

Blatchford Biomimetic Hydraulic Technology mimics the dynamic and adaptive qualities of muscle actuation to encourage more natural gait. Multiple independent scientific studies, comparing Blatchford hydraulic ankle-feet to non-hydraulic feet, have shown:

  • Greater comfort, reduced socket pressures
  • Improved safety, reduced risk of trips and falls
  • Smoother, easier and more natural gait
  • More evenly balanced inter-limb loading
  • Greater satisfaction
