The guy who used to work with Jonathan Edwards is pretty good -obviously…
He is based in Birmingham, or at least used to; he was coming over here at certain points a few years back and he had made my orthotics -very effective!
However, I am not sure what’s going on now, as he had a few personal issues; you could always try and contact him though.
The only thing I know is his name; if interested, I’ll email it to you…
