These are traditional Russian pointe shoes. Notice how tapered the toes are and how tiny the platform is! Compared to the wide, boxy styles of today, balancing on these small areas must have taken incredible poise and determination.
Tiny platforms were created for maximum stage drama. Audiences were wowed by this. They also placed higher demands on dancer technique; par for the course when it comes to the strict world of Russian ballet training.
Toes were scrunched in to accommodate the ever-narrowing toe box. It must have felt wonderful to take these pointe shoes off at the end of day.
