I was attracted to this as I have other Columbia products with "Omni-heat" and I think it is a great product innovation for pants, jackets, etc.

I loved the color choice too as they would be really visible and not hide in dark corners.

I take 9 1/2 or 10 m in my shoes - depending on brand & style.  I ordered a 10 here, but right away in the 1st couple of steps it was clear this design would not stay on my feet when I walked.

So they quickly went back - sorry, not a sizing issue I think a design issue.

I replaced with a pair from Cabela's of a different style (which are great).
