If you treat yourself to shoes that can take LOOK cleats, you can put Exostar track cleats on them and ride your toeclips and have a foot-bike connection that is just as good as clipless. (If you pull the toestraps tight for that connection, you do have to remember to loosen one before you stop. But falling over a a standstill isn't a big deal if you just relax and accept the fact that you just made a fool of yourself. Battered egos heal up quite fast.) You can google Exustar track cleat. you want the basic $20 cleat. not the lock-in cleat for track sprinters.
Those shoes won't be walkable but your everyday shoes will still work just fine.
