I'm not sure how hot the average hair drier gets but at the weekend I ran a hot half marathon.
In the sun the temperature must have reached 35-40C, add repetitive impact and a hot sweaty foot
and I can't see the material keeping its shape for to long.
Does the person stand or sit while its being moulded and what if they move during the 2 mins that it takes to shape the material?
Think I'll leave those.
