Seconded. I bought this semi-retired boot on Amazon and I love it, I use it every night. Doesn't require me to sleep in any unusual positions but it keeps my foot from being pointed, no matter how heavy your comforter is.
Better late than never. I've been dealing with PF since May, but have continued to do high-ish mileage without my PF getting any worse. So, can't fix it for you, but some days it doesn't hurt at all.
Things I've noticed:
Hope that helps!
not OP, but assume you are referring to the Straussberg Sock? I have Achillies Tendonitis and the sock helped me tremendously. But I personally found that it was poorly designed and uncomfortable. I made some adjustments to it myself to make it more comfortable, and that helped a lot.
Recently I ran across this brace a few months ago, and like it much better.
ETA: also, yoga is awesome too
Go on Amazon and order a brace to wear overnight. It works wonders:

I have that on and off. I stretch 2x per day with a focus on the Achilles and calf muscles. Also, I use this at night when I feel it flairing up: https://www.amazon.com/gp/product/B0057M3TWC/ref=oh_aui_search_detailpage?ie=UTF8&psc=1
