Sometimes after running, I notice a clear a of skin on tips of my third fth toe on my right foot. I can find no little mark I remember indicating a plantar wart. I carved a little it seems to go away. Now, 20 minutes later, I can't see it as much. It is not painful or feel solid now. Is it a sweat bubble?

It is not a wart. It may be a type of small blister induced by the friction created while running. I would not worry about it unless it starts to cause you pain. Have a nice day and please write back if you have any further questions.
