My favorite ones, but very expensive.

If you are pregnant though, I don't know if I'd recommend spending so much on shoes that you might swell out of in a few months. Perhaps look at those when you are PP.

So before pregnancy I really loved the Cole Haan Milly wedge with Nike Air technology. They are really comfy and I still recommend them BUT with the foot swelling that happens in pregnancy, I haven't worn mine in a while.

Instead, I've worn these Dankso sandals exclusively since 24 weeks and they will last me until the end:

I PROMISE they look better in person - they don't look quite so old-ladyish in real life. I'm an attorney in an office setting and they look just fine with both business casual and professional attire. They are SO SO comfortable. Functionally, they are like a dressier Birkenstock. They have a cushy footbed with a low wedge heel that gives just enough heel support to keep your back from hurting. But the best part is that the straps are adjustable and the bottoms have a rubbery, almost tennis-shoe like grip so that you're less likely to trip and fall. I've had to widen the straps 3 times so far, so I think that justifies the cost. Otherwise, I would have had to buy more shoes!

Other women swear by Sanuk Yoga Slings, but I haven't tried them personally.

I wore crocs mammoth flats exclusively when I was pregnant. I put them in the dryer and then let them cool off on my feet so they molded to me.

If they are not too casual for you, the TOMs wedges are insanely comfortable (and I have seen people pull the label off the back to make them less casual-looking).

@MaryM: I wore Born flats for my wedding too!

I also love Clarks clog/weges. They can sometimes run narrow though.

FYI, if you have a famous footwear nearby, they're having a bogo sale. I ended up getting some great deals over the weekend

Tieks!

@LemonLong: I have a pair of them. So comfy. It's a good fall shoe.
