I use Sorbothane's and they do help me. However I have found that to get them to fit properly I now buy 7 Sorbothane's (my feet size) and 7.5 boots. Of course it is important to check if one manufacturers 7.5 size is the same as another brand of boot. I find that some boots vary into 'small' 7.5's or 'larger' 7.5's sizes. For me it can make the difference between, a boot that I like to wear, to one that is uncomfortable. I also put the normal boot inserts on top of the Sorbothanes, for me it just feels more comfortable.
