ABSTRACT:
An exercise boot comprises a foot receiving member and a spring member positioned under the foot receiving member. The foot receiving member is formed of a unitary flexible piece of material which has integrally joined left and right symmetrical portions and which has been brought together. The spring member comprises identical top and bottom arcuate layers connected in an opposed relationship by a resilient strap and each defining a central slot. The symmetrical portions are provided with base portions which form a sole in the foot receiving member for supporting a wearer's foot and provided with hooks for engaging the slot of the top arcuate layer and thus secure the foot receiving member to the spring member while retaining the left and right symmetrical portions together in a boot configuration and in a way that most of the springiness of the top arcuate member is retained where it is connected to the foot receiving member. A ground engaging sole which defines an interrupted rib inserted in the slot of the bottom arcuate layer is further secured thereto with a pair of bands.
