I spend about 8-plus hours a day on my feet on cleanroom floors wearing uncomfortable shoe covers. I was concerned that these were not vented enough, but I'm not seeing an issue after a week of solid use. The shoe support makes any concerns fad away.

More importantly, the support is top-notch. I have no heel roll, and after standing for many hours my PF isn't even showing up as before.

Pro: Great support. I also finding myself heel-walking which is helping with my PF since my arch and heel are actual doing more of the work. I think my runners were "keeping me on my toes" a touch too much while just standing or walking. Fit is true to other 12-4E NB's that I've worn. The construction seems to be the same as other New Balance that I've worn. I don't think "break in" is needed with these.

Cons: Heavier than a running shoe... but that is to be expected with such solid inserts. I know the brushed leather will be stained and soiled soon enough so go with the solid non-brushed look, if it matters to you. I'd like to have a set like these, but with synthetic uppers for heat dissipation.

Just get them, if you feel your stride is "off" due to wearing running shoes instead of a good walker, or if your minor Plantar Fasciitis is acting up.

FYI: I picked up some NB inserts just to see how they work together. I also do NOT wear these on my days off, to allow the material to recover to it's initial shape.
