A swash plate-type compressor includes a cylinder block, a drive shaft, a swash plate, a plurality of pistons, and a pair of shoes. The cylinder block has a plurality of cylinder bores formed therethrough. The drive shaft is rotatably supported by the cylinder block. The swash plate is mounted on the drive shaft for rotation therewith. Each of the plurality of pistons is slidably positioned within a respective one of the cylinder bores to reciprocate therein. Each of the pistons has a pair of substantially semispherical cavities formed at an end thereof. A pair of shoes is positioned between each of the pistons and the swash plate. Each shoe has a semispherical portion adapted to be positioned within one of the substantially semispherical cavities of the pistons and a flat portion slidable along a surface of the swash plate. A first concave portion is formed in the flat portion. A second concave portion is formed in the semispherical portion.
