The hard plastic ones are the only ones I am familiar with. I am not impressed with those so I never use them. I'll try the leather on the tip. That sounds like a good suggestion.
The challenge is finding the right glue. What you need is a contact-adhesive that does not become stiff. The ideal type is used by cobblers but may be difficult to get. Here you can get a pretty good one sold for sticking Velcro on material.
Usually you have to put one coat on the surfaces and let it dry completely. You then put on a second coat and wait till it is 'tacky' - dried but sticky. Then force the surfaces together hard and WAIT. It takes at least a day to cure - I have not found a fast-fix method.
This lasts for months whereas I get through a pair of plastic protectors in an hour. The caveat though is that the floor needs to be smooth. The sectional kind - often used in competitions here (though dying out I'm glad to say) has ridges and these easily rip the leather off, which can be a surprise when you take your next step
