Stikets Shoe Labels are adhesive and are for all types of footwear. They stick to the insole of the shoe simply by being pressed firmly to the interior surface. It is very important to apply the labels when the shoes are brand new or, at least, that they are clean and dry before application.
For optimal results the insole must be made out of a non-porous, smooth material, such as leather, synthetic leather or synthetic materials. This way, the label will withstand washing machine and dryer use. On porous surfaces, moisture could affect the adhesive properties of the label.
