As a traveling business consultant,  I have worn these shoes for the last two years, and they are very comfortable.  They have been through many airports, and on many planes.  They are a good solid business shoe.  I am a bigger guy with wider feet, and it's harder to find decent 3E slip-on dress shoes, which is why I ended up buying these.  I like the look of these, a very classic slip-on.  They do run slightly large.  I normally wear an 11, but I bought these in a 10.5 and they fit exactly like I would expect an 11 to fit.  The 3E version of these shoes have a ton of space inside the shoe.  To me, that's a good thing, because I really like to use SOF SOLE inserts, but they are pretty thick.  With these shoes,  the inserts fit fine.

However,  there is one thing that I really hated about these shoes for a long time.  It may be related to the fact that I am heavier, but on certain floors,  the little plastic circle on the bottom with "Un" on it would make a very annoying sound.  After a long time, I just ripped those off, and the problem was solved.

As far as longevity,  I generally get about 1 year out of shoes before the heel wears, and I scuff them up too bad to wear.  These have held up much longer than that for me.  They scuff significantly less than the last couple of pair of Eccos that I have bought (which are more expensive). $120 for two+ years out of a pair of daily shoes (travel shoes at that) is a pretty good cost to use ratio.

I am trying out a different pair of slip-ons, but if they don't work out, I am going to order these again (and immediately remove that stupid plastic disk).
