Shear is the folding of underlying tissue when the skeletal structure moves while the skin remains stationary.A parallel force creates shear,unlike the perpendicular force created by pressure.As gravity pulls the skeleton down,any stretching,folding,and tearing of the underlying tissues,as they slide with the skeleton,can occlude vascular perfusion,which can lead to tissue ischemia.
