Those are gorgeous, but I can see how they could be hard to walk in.
Have you tried ankle braces? I use these for football: https://www.amazon.co.uk/MEDIZED-Stabilizer-Protector-Compression-Volleyball/dp/B01C1C3N7Q/ref=mp_s_a_1_10?c=ts&keywords=Ankle+Braces&qid=1644846130&s=drugstore&sr=1-10&ts_id=2826220031
I hope your ankle is feeling better. If not, or if it's slow, then this ankle brace is the type I like best. It fits in low or mid top shoes, and the comfort level stays pretty consistent throughout the day. I haven't used it for long hikes like you're doing, so you might want to have some sort of wrap to prevent hotspots from forming blisters. I think that'll give your ankle enough support to recover without giving up on our hike.

I also have a fancier one with a plastic frame and a hinge on one side, but I can't recommend it. It only fits with low top shoes, although that's usually not an issue for thru hikers. It doesn't stay put, so it can become uncomfortable quickly and you'll have to stop to adjust it. It's also finicky to get right. That may not be issues if you're playing sports with short bursts of movement, but hiking is the complete opposite.
