A horseshoe in which the heels are joined together by a bar of metal. The shape of the connection between the heels gives the shoe its name e.g. egg bar, heart bar or straight bar. These shoes are often used in corrective or therapeutic farriery.

Barstock is the straight steel rod from which horseshoes are manufactured. The barstock comes in various sizes (sections) and profiles. A flat bar has a plain rectangular cross section and is used to make plain stamped shoes or (hand-) fullered shoes. To manufacture a shoe from barstock, the correct length first has to be calculated and cut off from the bar.
