I ordered a size 9 extra wide.  what I got said 9 x-wide but the length...it's a tad bit long but, the heel. alot of people don't know that if you walk in the heel-to-toe method, the heel of the footwear is the focal point.  it should fit almost like a second skin.  this lock-in prevents slippage and that will help in the prevention, or at least delay, the onset of hot-spots and blisters.

now about what I use these for.  inside on a treadmill only.  been using them 5 days a week, for 3 to 5 miles.  I've worn out the treadmill.  the shoes are still looking great and none of the seams, stitching or adhesive points on the soles have failed.

next time i'll go with a 8.5 extra-wide.
