Interesting that you're seeing gladiators everywhere, Patience! I was just going to post asking if they were out of style, because I haven't seen them anywhere (in stores or in magazines), except for the cage variation.
So what I've been seeing are
--cork-heeled wedges (like those Lee mentioned) and also cork-soled platforms,
--high-heeled clogs
-- slingback heels
-- flat sandals with a strap around the ankle:

I'll be wearing my Swedish Hasbeens this spring and summer (the ones Julie mentioned!), and maybe my gladiators from last year if I can get away with it.
P.S. April -- that's like wearing a tea cozy on your feet! Alas, I am not so fashion-forward
