Abstract
An impact absorbing footwear device employs opposed planar sole portions engaged by a selective resistance coupling that biases the opposed planar sole portions in a non-linear manner in response to forces exerted by the wearer against the sole portion in frictional contact with a floor surface. The planar sole portions are disposed in a footwear appliance that takes the form of an athletic shoe sole. The selective resistance coupling includes a plurality of resilient deformation members that engage the planar sole portions in an opposed circumferentially aligned manner, selectively deform in response to pressure exerted by the wearer for preventing ACL and other impact related injuries, and recover to an undeformed rest position without breakaway to allow the wearer uninterrupted usage while dampening forces that surpass an injury threshold from the resilient deformation that allows the planar sole portions to temporarily misalign.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
