Hi all   sufferer of plantar fascists, so I need a stiff sole on a trials boot , which brand has the stiffest sole in the arch area

 

Id say possibly the alpinstars followed by the sidi. Absolutely NOT gaerne!

I find that Forma has the same wide fit as Gaerne but are much stiffer.  Once broken in Gaerne boots feel like bedroom slippers.  The Forma soles are much more durable and do not get chewed up by the foot pegs either.  They are slightly taller if that makes a difference.  I tried on Alpinstars but the fit was way too narrow.   

 

Forma is stiffer than Gaerne and alpinestars

I suspect it is a steel shank sole you are looking for and I think that is something found in enduro and MX boots but not so much in trials specific boots.  

Thanks everyone , looks like I can do better than the forma boots I already have

You need the old out of production ALPINE STARS NO STOP BOOTS  I would recommend going for 1 or 2 sizes bigger for toe comfort if you  find some on ebay ...... they come on fairly regularly normally almost new in condition in the UK . The soles are not very flexible compared to other boots.

I have flat feet and find the AplintStars Tech T to work well for me.  I haven't had a set of Forma's so can't say they are better or worse but I will say if you like toe room go a size up on the Tech T's.  Good luck.
