I had the predecessor to these shoes, the 955.  They were really comfortable shoes and when I finally wore them out I ordered the 956 which I thought would be similarly great.  Well, they weren't.  The ankle cuff, which in the 955 is soft and comfortable, is hard as a rock and digs into my feet.  I tried to break them in but I just couldn't.  Other than the ankle they are fine.  The shoe repair shop guy said there is nothing he can do about it, it can't be stretched or anything.  I guess if you have chubby feet with a lot of fat protecting the bones of your feet it might be ok but for me these are real duds.
