Casing shoe is a part of casing system.The casing shoes are threaded to the end of the outer drill string for penetration through overburden. It helps in seating the outer drill string into the bedrock, providing a tight seal for the drilling fluids to return to the surface. casing shoes can be used to ream the casing downward when advancing a casing string in an existing hole with the rod string still in place.

casing shoes are heavy duty diamond products which can match up to the toughest formations. With the use of very resilient matrix to optimize diamond retention, they will hold up in very abrasive, unfriendly formations
