I, for one, did not experience an odor problem. My model was touted as having an anti-microbial footbed that apparently prevents odors. Whatever it was, the product was remarkably effective in my case.
My great disappointment, and the reason that I cannot award 5-stars here and why I did not buy another pair at the beginning of this season, is the surprisingly short life of my shoes. On both shoes (left and right), the footbeds were parting at the mold seams and the webbing was pulling away from the shoes at these same points. This, just after one season of wear (frequent wear, including a few camping trips and creek wades, I should point out). I have a pair of Teva sandals that are years-old and still on the job.
So, I am giving another product a try this year; but I wouldn't discourage you from giving these a shot. Maybe you'll have a better experience.
