These SP blades were used primarily for competitions and important practices during the three seasons from 2016 to 2018. The frequency of use wasn't that high, but please be aware of some wear and tear on the plate. 7mm pins are installed. The plate hasn't deteriorated much. These are valuable thin-soled blades, as thick-soled blades are now the mainstream. Size: 27.0cm *Shoe bag not included.
