Apparatuses, systems, and methods for applying reduced pressure to a tissue site on a foot are provided. An apparatus may include an insole and a tissue contacting surface covering at least a portion of the insole. At least one portion of the tissue contacting surface is removable to form a void. The apparatus may also include a reduced-pressure interface for receiving reduced pressure from a reduced-pressure source, and at least one flow channel fluidly coupled to the reduced-pressure interface and the void.
