Shoe size USSR used the European (Paris point) system, but the Mondopoint metric system was introduced in 1980s by GOST 24382-80 "Sizes of Sport Shoes" and GOST 11373-88 "Shoe Sizes", and lately by GOST R 58149-2018. Foot lengths are aligned to 5 mm and 7.5 mm intervals. Standard metric foot sizes can be converted to the nearest Paris point ( cm) sizes using approximate conversion tables; shoes can be marked with both foot length in mm, as for Pointe ballet shoe sizes, and/or last length in European Paris point sizes (although such converted 'Stichmass' sizes typically come ½ to 1 size smaller
Pointe shoe to provide support. The second is the softening of the box and especially the platform on which the dancer balances. The other primary type of wear involves the exterior fabric. In pointe work the front face and bottom edge of the toe box are subjected to friction against the performance surface. This friction will eventually wear through the shoe's outer fabric covering, thereby exposing the toe box and creating loose, frayed fabric edges. Unlike a weakened shank, damaged outer fabric does not affect the performance of a shoe. Due to its unprofessional appearance, however, damaged fabric may render the shoe
