The Panmixer Paddles include the shoes (which are only available for sale with older panmixer models). The paddle set is the latest revision of replacement parts because the shoes are a high wear item with abrasive friction force from aggregate scraping along the floor liner; as well as the friction wear of the paddle vertical round bar. Since these wear away together, this is offered as a single piece replacement for the clamp mechanism of the spider head. The set of three paddles (including shoes) differ for each size of panmixer to ensure all the mixture is accessed for mixing.
