Title: Lawn aerating attachments for shoes and boots

Abstract: A cross bar is provided with a pair of plug cutting tubes one at each end thereof and being edge sharpened at the lower edge. Plug release cut away portions are formed in the tubes spaced above the lower ends. The cross bar is secured to the underside of the shoes or boots against the heel step with each tube being situated slightly outboard of the sides of the soles. Walking on lawns or the like causes the plug tubes to cut cylindrical plugs from the lawn which are expelled upwardly and outwardly through the plug release cut away portions.
