The O FIT Insole Plus II has the same fit that we all love but now has Cleansport NXT odor control, cushioning pods updated with Poron Vive for fatigue mitigation, as well as Obozs ACT (Adaptive Cushioning Technology) in the forefoot. Plus the new top sheet design blurs the lines of topography and footprints. All of this combined to make our best and most supportive insole to date.
