Abstract
A footwear construction including a sole and an adjustable heel element selectively rotatable about an axis of rotation to configure the heel element in a fitness mode or a stability mode. The heel element can include a ground contacting surface having a first performance contour and a second, different performance contour. In the fitness mode, the first performance contour is positioned rearward of the second performance contour to provide a rolling/rocking motion when the heel region of the footwear engages a walking surface in a gait cycle. In the stability mode, the second performance contour is positioned rearward of the first performance contour to provide a stable impact when the heel region engages a walking surface. The footwear can include an actuator to enable the heel element to rotate and locking elements to hold the heel element in a fixed rotational position. A related method of use also is provided.
