A blade outer air seal for a gas turbine engine includes a platform having a leading edge and a trailing edge, and at least one cooling cavity disposed within the platform. A pair of circumferential edges connects the leading edge and the trailing edge. An end wall protrudes radially outward from the platform at the trailing edge. A support hook protrudes radially outward from a leading edge of the platform. A boss structure protrudes radially outward from the platform and defining a solid kinetic energy path from an inner diameter of the platform to a radially outward facing surface of the boss structure, wherein the boss structure extends less than a circumferential length of the platform.
