A swash plate-type compressor includes a cylinder block having a plurality of cylinder bores formed therethrough, a drive shaft rotatably supported by the cylinder block, and a swash plate rotatably mounted on the drive shaft. The compressor also includes a plurality of pistons, each of which is positioned within one of the cylinder bores and reciprocates within the cylinder bore. Each of the pistons includes a substantially semispherical cavity formed at an end of the piston. The compressor further includes a pair of shoes positioned between each of the pistons and the swash plate. Each shoe includes a substantially flat surface adapted to be in slidable contact with the swash plate, and a substantially semispherical portion adapted to rotatably engage the semispherical cavity of the piston. Moreover, the semispherical portion of the shoe includes a saddle portion or a groove having a first curved portion and a non-circular perimeter.
