Wow, I hadn’t seen the harnesses! So cool! I don’t think they’ll fit on any of my Fryes - I’m still considering the Sachas to replace my ankle boots even though I already bought cowboy ankle boots.

Greyscale - in the info on the harnesses there is a list of boots/booties they fit best. The snow finally melted somewhat and I was able to get the sasha/harness out for a spin. So comfortable, I believe the heel might be lower than your booties. Very fitted and elegant but the best part of the versatility of the harnesses, I am beyond love for these boots. I've already bought a back up pair. But they really vary sizing wise. If you try them you might want to try a few pr if they are a smidge big or small, trust me there is a pair that is just right!
