All of my work shoes are Cole Haan, and I'm a teacher who spends at most an hour a day sitting. Yes, they are so, so worth it. I know Endless has a bunch of the Air Talia wedges on sale right now, too.
I like them bc they provide cushion but aren't too bulky to where they make my shoe fit tighter like some of the gel kinds can. I srsly buy these in bulk and use them in many of my heels.
Cole Haan shoes are definitely worth it. The heels are very comfortable for heels and the flats are amazing. I have the Air Talia mid heel and really like them.
I've had luck with Nike Air Cole Haans; if you don't want to pay full price, keep an eye on their website, they usually have good sales. Also, they have outlet malls.
