The pressure relieving device is intended to provide users with a stress relieving support surface that is customizable. To that end, the device includes a sleeve with one or more compartments that may be individually filled and refilled with a deformable media. The deformable media further includes a mixture of both non-rigid deformable and rigid non-deformable particles that enable the device to conform to any shape when acted upon by a pressure and recover back when pressure is removed. The device may act as a footwear component for use as a shoe insole insert which may be customized by the user to relieve pain in the areas of foot where most required. Accordingly, the footwear component adapts to the user's foot pattern while standing or moving. Furthermore, the device is durable, washable and reusable, and may be used with open shoes, closed shoes or even without any shoes.
