Similarly, resilient member 36 expands into channels 30 of exposed cavity 22 upon weight bearing of the forefoot. Resilient member 36 retracts from channels 30 upon unloading (referred to as toe-off). It should be understood that, by virtue of the resilient nature of resilient members 34 and 36, the resilient members return to their original uncompressed state upon unloading of the foot.
