Thanks seeing as this is a old post but I was gonna ask the same thing and still a bit confused can i just ask should i buy the £10 Gel arch support insoles or a pair of £100 custom ones?
I always no matter how i run get foot cramp and its so annoying I am never gonna be able to complete a triathlon at this rate.. noway! Has anyone got any suggestions on what insoles i should be buying? I found those ones on the nuovahealth website which look okay... will they be?
