I purchased these at a military shop in Akihabara, but unfortunately, they don't fit (they give me blisters), so I am sadly putting them up for sale. They are "OP.GEAR British Prison Officer Boots." HM Prison & Probation Service is an executive agency of the Ministry of Justice (MOJ), responsible for correctional services in England and Wales. In 2004, it was established as the National Offender Management Service (NOMS) by integrating the headquarters of the National Probation Service and HM Prison Service, along with some existing functions of the Home Office. In 2017, some of the agency's functions were transferred to the Ministry of Justice, and it was given a new name.
