In reply to JamesWoolley:
* Take this with a pinch of salt, I once trained as a boot fitter but it's been many years since I did any!
From what you describe, it sounds like they may be the right size for length (or close to it) , but that you may have too much volume in the boot. Did you get the boots fitted during purchase? If so, did you get this problem when tested on the ramp, and if not, what was different - socks, lacing etc can make a difference. I'd play around with thicker sock combo's and the forefoot lacing first before anything else.
Superfeet are meant to help stabilise the foot for those people whose feet collapse outwards too much on impact, you need to be tested to see if you need them. Volume reducers (which it sounds like you may need) usually go under the footbed. If you continue to have problems, I'd take your boots along with your usual sock combo to a good shop with an expert boot fitting service and get them to have a look and see what the problem is and how best to fix it.
