Silcone sheet or similar

You can get heatproof Silicone rubber baking trays. Just the ticket to locate and destroy one of these I suspect. This sort of thing:

Or how about high quality butyl pond lining from a garden centre?

Silicone isn't exactly springy. However it's heat-resistant and easily available from cookery shops as biscuit baking sheets. Lidl had it a while ago, for their usual cheap prices.

Plastazote is also worth a look. It's a dense mechanically-blown foam. Cheap in A4 or A3 sheets from craft shops, Hobbyworld etc.

Neoprene (wetsuit) offcuts are cheap from bigger dive shops, and Evo-stik 528 will laminate it into blocks.

For other foams, such as closed-cell polyethylene or dense neoprene (good packing foams) then talk to a commercial foam processor. They'll sell to anyone, in any thickness, but minimum order is usually an entire

It depends on the type - but the baking sheet stuff wouldn't be flexible and springy enough, I agree.

Thanks very much. Those sound useful ideas.

Yes, I had got that far! I just want to make two boot instep pads and, if suitable, some bathtap washers. Don't ask, in either case :-)

Well I would wonder over to DSA orthotics as they make insteps and stuff like that.

I am customer BTW and have no other interest.

Or, for ready-made shoe/foot "things", Cosyfeet:

similarly - only a customer, no other interest.

================================================= You might consider 'Sorbothane' for the instep pads. It's a close match in texture and feel for human flesh.

My local lidl (NW london) has some nice big silicone baking trays left.

The large one cut in half covers both the bottoms of my double oven.

I'd agree that sorbothane, is the best stuff for insoles.

Contact your local friendly chiropodist who might be able to advise you where to get a sheet of the stuff.
