Achilles tendonitis right before a 10-day hut-to-hut hike. Footwear advice?

Hi everyone,

I recently came down with Achilles tendonitis, and in the most frustrating way possible: I was completely fine, went for a deep tissue massage, and walked out with it. The therapist worked directly on my Achilles, which felt weird and uncomfortable at the time, but I took too long to tell him to stop. Lesson learned.

The problem is I'm hiking the Alta Via 1 in the Dolomites soon, ten days hut-to-hut, and I'm now second-guessing my footwear. I have a pair of Scarpa Kailash GTX boots that were gifted to me, but they're basically brand new and I've never properly worn them in. My other thought was to buy a pair of trail running shoes instead. I prefer trail runners generally but my current Altra Lone Peaks are too run down for this trip. Been considering the Hoka Speedgoat7.

For those who've dealt with Achilles issues on long hikes: what makes the most sense to protect the tendon? Stiff boot vs. trail runner? Anything else that helped (heel lifts, lacing tricks, etc.)?

Thanks in advance!
