Grishko suede caps (also known as suede tips) for pointe shoes.
If you do not wish to darn your pointe shoes, applying suede caps is a great and faster alternative. Prevent the satin from the platform coming off, get better grip and traction en pointe and extend the life of the platform.
Can be trimmed down and applied with fabric, PVA or other appropriate glues. I have a video on how to apply them on my YouTube channel/Facebook/Instagram.
