Abstract
An airbag for shoes has a plurality of elastically compressible cylindrical cushion members which are interconnected in a predetermined array by a connecting plate. The cushion members/connecting plate combination is encapsulated in a casing. The cushion members, connecting plate and casing are joined together to form an integral unit. The cushion members have a spiral groove formed in their outer surface which increases their compressibility during the initial phase of compression.
