Orthodics

What think of orthodics both custom and off shelf and with respect to gokhale methods?  i usually have to wear half size larger to fit my custom orths in shoe but i have not worn much over last year and a half but my podiatrist said to get back into them (she was not one who prescribed in first place).  Lately been using Rockport Eureka shoes.  Note i have peripheral neuropathy on bottom of feet which causes severe burning tingling and pain so walk limited to about half to 3/4 mile and other instabilites around ankle knees and hips.   thks for any input.
