Abstract
A reversible insole having a composite structure in which a base insole layer of resilient cushioning material has fabric bonded to its opposite surfaces. Protuberances extend from one surface so the insole may be worn as either a massaging insole or a comfort insole. The insole may be printed with a representation of a reflexology chart and protuberances located to massage selected areas of the foot. Apertures are provided for air circulation. In an alternate embodiment the protuberances are selectively attachable to the base insole.
