i've had some issues with the ligaments in my foot for a while and the best thing to do is freeze a water bottle then roll it on your arch for a few minutes at a time before bed. it's weird and a little uncomfortable but pretty much erases the pain in the morning.
This. If you wanna go even mo betta, I sometimes fill a styrafoam cup about half way with water and then put it in the freezer. Once it's frozen, i just peel the styrafoam off and massage my muscles with it. It's basically just a giant ice cube, but it works wonders cause you can really massage the cold into the muscle.
Also, Tiger Balm can help. The only issue is the skin on the bottom of your feet is thick, so it takes a lot of Tiger Balm to feel it, and you develop a tolerance to it over time. So I try not to do it too often, but when I haven't skated in a while and I go at it like a mad man, I buy Tiger Balm on the way home for feet, thighs, calves, back, whatever.
Just don't get it anywhere near your junk, it'll ruin your entire night, trust me
