Looking for custom orthotic shoe inserts makers

I need a good pair of orthotic inserts custom-made for my feet. Any recommendations in Rayong province?

So far, Bangkok Pattaya Hospital is the only source I've found that makes proper orthotics, but they are quite expensive - Bangkok Rayong Hospital does not offer these. There is a mall chain called Fixifoot but their prices are twice the hospital prices. Any recommendations would be appreciated.
