A traction-enhancing cleaning kit for allowing sports players to clean and dry the soles of their court shoes while in-play. The cleaning kit comprises a gellified shoe cleaning fluid (3), and a shoe-attachable cleaning and drying device (1) comprising a gel-absorbent cleaning/drying cartridge (2) removably secured by hook-and-loop to a carrier platform (4), which is in turn secured along the forefoot of the sneaker by its laces. The cartridge (2) includes an encapsulated viscose rayon microfiber panel (20) backed by a moisture-impermeable layer (30), and held captive in a plastic frame (10). The frame (10) includes a raised wiping lip (114) surrounding the panel (20). In use, the player need only swipe one foot over the top of the cleaning and drying device (1) attached to the other foot, brushing the sole. One swipe wets and squeegees dry, and the process is repeated for the other foot.
