Hi my ds2 is 16 and he normally gets black piedros boots.but now he got swopped on to nimco boots and came home with a pair b4 they broke up. They are two wide and too big , Anyhow the orthotics rang me today and said they was just gonna pad them out .? They fit me and I'm a wide size 8 he can't even walk in them and I've not an idea how to clean them as not sure what they made of does anybody know ?
