Abstract: A golf practice device that provides the feel of natural turf is formed of a mat with an insert including a continuous, rotatable belt extending around spaced, parallel rollers to create a moveable horizontal, ball supporting, upper surface. A tray for holding a deformable material is located beneath said belt upper surface, so that striking of the belt upper surface depresses the belt downwardly into engagement with the deformable material while rotating the upper surface of the belt toward the front of the mat to simulate the feel on striking a golf ball on a natural turf or sand surface.

Abstract: A passive platform elongates under the pressures of ambulation directing fluid wave within a bag portion. The neutral subtalar joint position is attained by adjusting elastomeric assisting straps.
