I'm retired, and wear "athletic shoes" mostly everywhere.  I actually got these Avia 325s because they are totally black, and I intend to wear them when my multi-colored Nikes or Sauconys might be too flashy [like at the courthouse, for jury duty].  I've only worn these for a couple of sessions on the treadmill, so these are my preliminary impressions:

Pros: Very inexpensive.  The uppers are well-sewn, and all the glue joints appear to be uniform & well-bonded [I hope the previous glue-failure problems have been corrected].  Adequate cushioning; the heal has Avia's "cantilever" technology, which is okay, and works if you're a heavyweight, as I am [it takes some "weight" to compress the concave heel].  No problems with the insole sliding, as some reviewers have reported [though I have had that problem with a pair of Nikes, and it's very frustrating to remove your shoes to re-position your insole.]

Fairly aggressive tread [2 different materials], with flex grooves.  I deliberately walked on some wet tile in the laundry room; good adhesion at a walking pace.  I sprayed some WD-40 on the concrete garage floor, and was able to skid.  But, I could also walk safely if I used a bit of care.  I guess what I'm saying is, if you can see a slip hazard, and walk normally or with some care, you'll probably be fine.  But, if you're rushing around a factory floor, or hurrying about a commercial kitchen floor, you could definitely skid on something slippery.

Finally, it has a conservative appearance, suitable for an informal workplace.

Cons:  I got size 11.5 4E.  The toe box fits a bit more snug than my New Balance shoes of the same size [about on par with Nike's sizing for 4E].  The vendor's or Amazon's caption says this is a "walking shoe;"  really, you could comfortably walk a couple of miles perhaps [I walked for several miles on the treadmill, just to test them out].  But, there are more comfortable walking shoes out there, though they are more expensive.  I think this is more of an office or work shoe.
