How do I position the Flex Up?
First, there's a right Flex Up and a left Flex Up (the feet aren't symmetrical), but that's marked on them.
_ Next, there's a top and a bottom: the foot drawn on the Flex Up must be facing downwards.
_ All that's left to do is simply insert the Flex Up into the pocket.
_ And above all, close the little Velcro marker: Velcro closed = Flex Up correctly positioned.
Why is the Flex Up only compatible with Decathlon snowboard boots?
The width and 3D shape of the boot tongues (longitudinal and lateral curvature) are specific to each brand.
We therefore first defined a unique 3D shape for our tongues, based on the anatomy of the foot/shin, and then developed this accessory to fit our shoes perfectly.
If the Flex Up fits shoes of another brand, so much the better, but this is by chance, as it is impossible to make it compatible with all brands.
Elastic property
Flex Up will work in flexion, but in a deformation zone where it remains largely elastic, i.e. it will not undergo plastic or permanent deformation.
In other words, your Flex Up will never age, and may even be used again for your next pair of snowboard boots Decathlon.
