These are excellent tips and provide better traction in most places where I walk than carbide tips. They're also quieter and do less damage. The only thing is that they are force fit, and only work well when they are on the carbide tips (as opposed to the hard plastic tips). I have lost one already because the force fit isn't snug enough. I would prefer a tip like this be screw in, like the carbide tip. Seriously considering glueing the next pair to a carbide tip.
For those of you who want a force fit so that you can use the steel tips, these tips are well protected so that steel tips will not penetrate these.
