Modular and exoskeletal foot fittings use a connection plate at the interface between foot and adapter.
Moulded polyurethane feet benefit most, since the material compresses and creeps under sustained local load.
Heavier users place higher clamping loads on the foot material, which is where load spreading contributes most.
Feet used in wet or dirty environments are helped by a plate closing the moulded recess against ingress.
Foot changes and refits give the opportunity to inspect or replace the plate while the assembly is open.
Clinics holding foot stock benefit from plates held alongside, so a build is not delayed for an accessory.
Services fitting across a size range are served by plates covering several foot sizes, where the manufacturer supplies them that way.
