I searched and couldn't find relevant info. I apologize if it has already been covered many times.
I have two pair of boots and both are causing inner foot pain around the inside of the heal. I have have gone to two local shops to get help, but I am still having issues. Boots are Cochise 120 and Lange RS 130 Wides.
I would say I have high arches, but haven't experience lack of support issues in other activities. That said, at shops suggestion I bought some green sol insoles and then some sidas "volcano" insoles on my own to test and am still having problems.
My thoughts are the heel pockets are not wide enough on these boots for my overall wide feet. The insoles also cause extra pressure on my high instep, but that I have always managed by not buckling the bottom two buckles, even without insoles I have instep issues.
The boots have also been punched, but it was just where I told the fitter to punch and it appears to have re-formed a little to original shape.
I drew a circle around the area of pain I am experiencing on a stock image. I also have pain in heel directly below circled area as well. After skiing the area forms a painful hard lump of tissue that lasts a couple days. Maybe someone has had experience here and can suggest that I need a boot with a big heel pocket, higher arch support, another potential issue....
