Pure rubber once vulcanised can not be melted or the tires on your car would melt under heavy braking.
What temperature does silicone rubber melt.
After temperature cools down it resets and transforms to solid with time.
Most modern shoe soles are not rubber as in natural latex based but are some form of plastic heat will melt most thermoform plastic but the problem will be making a suitable mould for the sole.
While most plastics will begin to melt at high temperatures silicone does not have a melting point and remains solid until combustion occurs.
Also notice that silicone has high rubber temperature.
At high temperatures 200 450 o c silicone rubber will slowly lose its mechanical properties over time becoming brittle.
The closer that your material is to the limit of your rubber temperature range the faster the material will degrade.
Neoprene exhibits good chemical stability and maintains flexibility over a wide temperature range.
Neoprene also polychloroprene is a family of synthetic rubbers that are produced by polymerization of chloroprene.
Silicone rubbers are often one or two part polymers and may contain fillers to improve properties or reduce cost.
Rubber begins to melt at approximately 180 degrees celsius.
Here is a rubber temperature chart that provides high and low temperature ranges for all popular rubber materials.
This is a polymer containing silicones with atoms of oxygen carbon and hydrogen.

Silicone rubber has exhibits unique behavior at elevated temperatures.
At low temperatures around 5 c to 6 c there is a risk that rubber hardens because of crystallization.
When adhesive silicone melts it remains intact at its place and does not flow.
Welcome to our rubber temperature range section.
For example if heated up to 150 c you would see very little change in the silicone even if held at this temperature for a very long time at 200 c the silicone will slowly become harder and less stretchy with time and if the silicone was heated up to a temperature beyond 300 c you would quickly see the material become harder and less.
The optimum temperature for rubber is 20 c.
