It doesn't affect the pad material, it just kills the glue so the pads just slid out. I have done this to about 5 different pairs of pads all different material ones and i have never noticed the material to go 'off' Tom.
Put them in the oven for about 5-7mins at 150 degrees and then they should pull out really easily but be careful they will be very hot!, i have done this many a time so it does definitely work. Tom.
The Try-All shoes are good, but they don't last that long at all! If i was you, i would pay the extra money and buy some Ribo's. I have had both sets and the Ribo's are by far the best. Tom.
