I did a little experiment with clear silicone. This is the more expensive clear that is paint-able. Given we are not painting it, I don't see why one would need to pay twice as much if this works.
Question: What is the shore hardness of this stuff?
The test piece I have made myself is soft and grips really well to the smooth tiles on my floor. So maybe this might be too soft as the base sole, but what about the sides?
And yes it back lights quite nice
Blue at the top, red for Taff83 in the middle and green at the bottom just so I could see if my NEO shoes are worth doing.
Feedback please!
