Hi all. I have recently had orthotics inserts for under my heel made up as i have properly wonky feet. But its thickness means i can not use them with my sorbothanes in my boots. So can anybody recommend a thin insole similiar to sorbothanes but without any built in supports, just a plain flat one like you get in trainers. Currently i am using cheap insoles from a pair of trainers but after a recent CFT the balls of my feet had taken a pounding with blood blisters forming, so some shock absorbance would be much appreciated. Thanks in advance.
