That's exactly how I feel about my Oreos, I've been wondering if my pair was from a bad batch. The ones I own are neither soft nor comfortable.. They fit good but leave my feet sore after wearing them. The Columbia 4s I own are softer to the touch but still not all that comfy, maybe 4s just don't contour to my feet well. I'm thinking in the future I may go a .5 size bigger so I can throw a thicker insole in em.
On a side note: I have checked some other pairs in store and they seem to be the same material. The tumble looks nice, but it's kind of stiff and has a gloss to it.. Reminds me of the French Blue 7s. Soft to me is something like BOB Xs or better..
