Abstract
Abstract A heel-counter stabilizer is provided for attachment to an athletic shoe having a heel member of resilient material. The stabilizer is adhesively bonded to the exterior of the shoe in a manner which provides both vertical and longitudinal support and bracing between the shoe counter and heel member. The stabilizer is particularly effective to counteract counter "run-over" and heel wear caused by either pronation or supination. It also helps to prevent compression and blowout of the midsole and heel wedge.
