First of all, I'm mesmerized by the FAB colors in your top and how they're showcased by the nice fitting white capris!

If you are going to spend that much on sandals, wait for a pair that you can get really excited about.

I voted Yay. I work on my feet. I have fashionable shoes, and I have functional shoes. These are right in the middle and I think that's great. The top (straps and color) are fashionable. The less fashionable sole and heel wouldn't be visible enough to bug me. Your camera angle makes them more visible than IRL when people see the tops more.

I think keeping them for a bit to see if there's something better is a good idea. Not because I wouldn't keep them but because you seem to be hesitating.
