Yup the 285 has a similar fit to the 230, the same low profile ( 2 cushion) but has a sticky rubber Roclite lugged sole and a rand for protection.
My new 285s arrived yesterday. Much snugger fit than 305/315. I was sceptical re sticky rubber but a 20min walk in them was interesting Rand is relatively soft and I suspect is more to protect shoe from wear and tear than runners' toes
