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 the type of material used. A shank's thickness may be consistent throughout or it may vary along its length to produce different strengths at select points. For example, slits may be cut across a shank at demi-pointe to enhance roll through. Also, a shank's thickness may transition at some point along its length in order to implement differing strengths above and below the transition. Standard pointe shoes typically have a full shank, in which the shank runs the full length of the sole, or fractional (e.g., half or three-quarter) length shanks. Many pointe shoe manufacturers offer a choice of shank
