The footbed inserts on Flex-on stirrups (similarly to the decorative inserts on the frame), can be easily changed by the customer to switch from one footbed type to another, or to replace the footbed if it has become worn or damaged (note this does not apply to the Endurance model). We stock replacement inserts for the four main types: inclined or mixed, with ultra-grip (ie with metal studs for extra grip) or grip (without studs). The inclined type is also suitable for flat footbeds.
For an explanation of the difference between the footbed types, see the footbeds section of our overview of the customisation options available with Flex-on stirrups here. Note that based on our long experience our strong recommendation for UK-trained riders - for both jumping and dressage - is the mixed inclination type.
Fitting instructions: Under the footbed find the two small phillips-head screws that hold the footbed insert in place. Carefully remove the screws, then push through the holes with a suitable thin object (eg bradawl or paper clip) to lift the insert off its surround. Pull the insert backward (ie toward where your ankle would be) to free the insert from the locating slots in the front of surround.
To insert the replacement insert reverse the above steps.
