Sneaker Insoles New, but opened for photography. Contains 8 small cushion-type insoles. Please stick them to the underside of your sneaker insoles. I have bunions and no arch, so I used these by sticking them to the underside of my insoles when wearing sneakers. I think they can be used in various ways. They are about 1mm thick, but you can feel a difference in comfort. Sizes: 9 x 4.5 cm 6 x 2.5 cm 5.5 x 3.5 cm 5 x 3.5 cm There are 4 different sizes. Please make use of them.
