It may be time to seek a podiatrist's opinion. My toes twitch/bend involuntarily and I have to reach down and "correct" them by cracking them, as much as that may seem like an overshare. This condition is referred to as hammer claw but may have other names. There are special socks that foot doctors recommend that basically separate your toes. They are typically worn at night. This feels more like a cramp than a twitch, however.
