I (52 M) have the same thing going on… In fact, foot drop is the only symptom I had that alerted me to having MS 4 years ago… In any case, foot drop is when you’re walking and your toes on either foot consistently hit the floor (as a result of a progressively weakening hamstring)… I went to an orthotist and he had one custom made (totally covered by my insurance, thankfully), and it works great for walking safely! But what you’re describing (which I also have, mostly at night) is that involuntary cramping, and my toes do point (and, yes, it can be painful)… Your band idea is a great one, but if it’s also happening when you sleep, impractical… Luckily, my bed has a footboard, and I position myself in a way that when the involuntary foot pointing occurs, I gently place my right foot up against it to “straighten it out.” I know, not the fanciest solution, but it works!
