Abstract: Footwear, insoles, inserts, kits and methods effective for acclimating a user's foot to a different heel-toe ramp and/or foot strike pattern are provided. Footwear, insoles, inserts and kits of the present disclosure have a region of adjustable thickness which allows the user to gradually change the heel-toe ramp of the user's foot, and/or gradually adapt to a new foot-strike pattern. Regions of adjustable thickness may include a layered pad, inserts of varying thicknesses which may be used with the footwear or insert, or a material having a thickness which changes with the rate of applied force.
