Configurate Sla monitor command at dual ISP at cisco router
if you don't track the static route then the backup will only come up if primary line protocol is down, it's ok for point-to-point links but not for multipoint interfaces which may still be up while the other end is down.
Furthermore without the tracking even if primary link is ok but there is a problem in the ISP network then this route won't be accessible via this ISP but your primary route will still be in the routing table.
So yes it's better to track an ip sla object and link this tracked object to your static route but you can do with only tracking on primary with one ip sla object because when the track object goes back up then the primary route with lower AD will get installed back in the routing table and your backup route will get removed from the routing table.
