Can someone explain this to me?

Our toes do have toe tips. We don’t have much need for saying it unless we are talking about walking on our toes.
Fingers and their tips are much more prominent in our minds due to proximity and constant use. As for “tipfingering” … let your fingers do the walking?

sounds like a question for george carlin

You never heard of someone tip toeing

Never thought of it like that

If it's Possible to do pushups with their Pinkies, then they can Tip finger
