Footbeds (e.g., in footwear, socks, etc.) for engaging a plantar surface of a wearer's foot include one of the lateral or medial sides having a smooth or substantially smooth feel or surface while the opposite side has a textured feel or surface, e.g., by providing plural raised areas that define the textured feel or surface. Depending on the location of the texturing (lateral side or medial side) and/or the type of ambulatory activity (e.g., running or walking), lower extremity movement during the activity may be affected, e.g., to reduce pronation, reduce maximum eversion, reduce rearfoot range of motion, reduce eversion velocity, reduce plantarflexion when pushing off during a step, reduce inversion at heel strike, reduce eversion range of motion, reduce maximum internal tibial rotation, to increase stability during cutting motions, etc.
