Shoes for HIIT?

Hello people of FB! First of all, THANK YOU KELLI AND DANIEL. You guys are amazing and when all of my friends and coworkers are complaining about their gym memberships, I basically have 2 free personal trainers. You guys do fitness right!

Now my burning question: what kind of shoes does everyone wear for HIIT? I wear under armor running shoes or Nike running shoes and I find I have little stability with side to side jumps (lateral jumps, any kind of jack, even jump squats)... and these are some of my favorite!

I sprained my ankle a few years back and don’t want to risk doing it again with unstable shoes... anyone have a good recommendation?
