I did some arithmetic. Its your turn.

It would be better if you did the right arithmetic.
Then you would know what's under an ice skate.

How about i call them quantum virtual delocalized quasi free hydrogen ions.

How about you stop making up dross?

Dregs waste scum rubbish worthless corrupted impure.  I agree. Like modern science. Like the Nobels. But the times they are a'changin.

I showed u my 30 N/mm^2.  Now u show me yours.

An ice skate is something like 3 mm wide and about 150 mm long.
So that's about 450 square mm
And a 75Kg skater puts about 750 N on that area.

So that's roughly 2 N  per square mm or 2MN per square metre.
Roughly 20 atmospheres pressure.

Now the depression of freezing point of water with pressure is about 0.01 degrees per atmosphere.
So the melting point of the ice under a skate is something like -0.2 degrees  Celsius.
So, if the temperature was below that (and it almost always will be) the material under a skate is solid ice, rather than liquid water.

So, even if there was some magic form of liquid water, it couldn't possibly be relevant to ice skating.

Why didn't you do a little arithmetic when I told you to, to avoid foolishly sticking to an impossible story?

Wiki told me that the pressure causes melting paradigm was discarded years ago. Me myself i never ever thort other than friction was the cause of melting, which is the current paradigm.
 
I also see that the lack of melting problem & hi friction problem comes in at about -100 C. 
And that minimum friction happens at -7 C.

My EZ idea at the bottom of #16 re four possible scenarios for repulsion & friction might be useful in explaining that there -7 C minimum friction. How might u explain it? I apologize for the dross acronyms -- qfp means quasi-free-protons, & EZ means exclusion zone phase of water.

If there is very little bulkwater & qfp tween the 2 EZ zones then repulsion will be strong.
If there is a small amount of bulkwater & qfp  then the repulsion will be weaker.
If there is a goodish amount of bulkwater & qfp then the repulsion will be strong.
If there is a lot of bulkwater & qfp then the repulsion will be weaker.

Something to think about.
How would a gecko or spider fare if they tried skating on ice?
How would we fare if we tried hairy skates? Or hairy skis?
