These are literally STEEL PLATES
I think the only way anyone could describe these as "flexible" is if they were comparing them to, say, steel plates or railroad spikes. Imagine cutting an insole shaped piece of 1/16" steel plate and slipping them into your boots. Better yet, buy these and slip 'em into your boots because that is EXACTLY what they are -- inflexible steel plates!  Still better?  Don't order these and keep looking until you find a seller who actually knows the definition of the word "flexible."  Total waste of time.
