The name says it all and it's another footdisc first. Heel cups (the part of the insole that your heel sits in) have always normally been rigid in the belief that if you can control the heel you can control the foot. With more and more research indicating that this is not the case (and along with an acceptance that your shoe's design and fit play a critical role), footdisc decided to do something about it:
footdisc's 'Auto Fit' system is designed to enhance the performance of the heel by:
1) Increasing Shock Absorption: The heel bone is a good shock absorber with both the bone and surrounding fatty
tissue playing a roll. The auto fit cups the heel ensuring that more of the bone and fatty tissue receives impact
shocks and therefore absorbs (attenuate) these impacts using your body's own mechanisms.
2) Reduce excessive heel motion (speed and movement): simply your heel will be held perfectly in the heel cup and
the heel cup will sit into the shoe like it was custom fitted. Therefore the shoe's heel counter will be more effective.
3) Allow the shoe features to work: An extremely large proportion of your shoe's motion control, support and
cushioning features are situated between the forefoot and the heel, so why block these with rigid/plastic insoles?
footdisc heel cups are soft and can only enhance these features.
