PRODUCT
• The NAVIGATOR is a multi-axial unit with integral spherical ankle
• Resilient Keel• The package has a
foot shell and proximal pyramid

Features
Ankle joint positioned within foot enclosure to mimic natural foot action
Keel provides 4mm deflection at 1000N to support and smooth rollover phase
Plantar flexion angle increased by 100%, from 6 to 12 deg, on original Multiflex

Ankle motion
Lowered ankle centre gives improved plantar flexion action at heel strike without reducing support through mid-stance or toe-off
![Page 5: The Navigator Foot](https://reader036.vdocuments.us/reader036/viewer/2022062322/568146bc550346895db3eff9/html5/thumbnails/5.jpg)
Benefits
• Realistic ankle joint position for a more natural look and feel
• Controlled ankle motion enhanced for comfortable and symmetrical gait
• Improved rollover characteristic from ergonomically shaped resilient keel
• Lower build height to maximise individual assembly options
• Warranty 3 years on all non-replaceable parts

Uniqueness
• The joint position provides real plantar flexion at H/S
• Reduced heel compression means less shortening at H/S
• The action preserves the knee because it allows the load line to pass through the knee

Navigator
• The deflection graph shows that the resilient Navigator keel stores energy and enhances the foot action by providing some springiness at toe off:
• Deflects 5mm for 100kg wearer at toe off.

Keel Info.
• Resilient Keel made from super tough nylon + 5% glass + 5%PTFE + silicone oil
• Result the “Slippiest” keel we’ve ever made!
• 4 keel sizes

Foot Action
• Increased plantar flexion• At 12 deg it approaches
normal• Dorsiflexion similar to MF• Lower centre of
rotation..more natural• Ankle rotates rather than
heel volume deflecting

Foot Testing
• Keel tested to 2 million cycles A125 at 1Hz with minimal creep because of the glass reinforcement

Torques
• Use regular tools to change the ball: there is a pin available for optimal alignment
• Torque (Loctite) to 15Nm
• Tighten diagonally

Cosmesis
• New shape as identified by market research
• Enhanced curve over heel to aid shoe retention
• Finish cosmesis by glueing directly to shin foam or by using a plastazote interface
