This pointe shoe glue is the first hardener formulated by a pointe shoe manufacturer specifically for strengthening and increasing the life of a pointe shoe made of paste and leather. When applying the hardener to pointe shoes, dancers can feel the shoe heat up due to the chemical reaction of the hardener working. The viscosity of this hardener prevents the shoe from having sharp peaks or edges of glue after application. The fast drying formula sets in 30 seconds, and cures completely in 24 hours.
