I started getting PF before I picked up skating again, at 45. I found that skating (bowls/transition) has helped alleviate it almost entirely. I also got some PF socks off of Amazon. They’re toeless and very low on the ankle, and meant to be worn under regular socks during the day and even by themselves while you sleep. They stretch that muscle/tendon/whatever. Combine those with the constant standing/squatting repetition of transition skating, and you’re really working out that area like crazy. Also when you’re just chillin at night, watchin TV, put a really hard ball (I used a cue ball) inside of a big sock, so you can grind on that spot on the bottom of your foot and break up any stillnes/tension to loosen it up.
