A foot and ankle strengthening device is an apparatus used to provide stimulus to muscles typically weakened in people who suffer from various foot and ankle problems, particularly plantar fasciitis. A pair of angled surfaces is used to reinforce healthy foot arches. The apparatus comprises a first foot-bracing platform, a second foot-bracing platform, a textured roller, and an elongated balance block. The first foot-bracing platform is a surface against which a user may place a foot for support and appropriate positioning. Similarly, the second foot-bracing platform provides a surface for the user's opposite foot. The textured roller is a generally cylindrical device that enables the user to apply targeted pressure to specific pieces of the user's foot or ankle. The elongated balance block is a generally rectangular prism-shaped protrusion that, in the preferred usage of the apparatus, provides the contact point with the ground.
