Hi resently my daughter 12 and son 11 have started a new high school because we moved house resently. Their new school allows them to wear plain black lace up plimsolls instead of school shoes so I bought them both the lace up plain black primark plimsolls for £3 a pair which they wear as school shoes. Their school has a basic polo and jumper uniform. Would you let your kids wear plimsolls as school shoes ????
