So, I'm back with an update on the Tretorn sneakers. I bought two pairs:

I kept the metallic leather pair and returned the black canvas pair. I have been wearing the metallic leather pair several times a week and have found them quite comfortable - they are definitely 8 hour shoes for me. Yay! I ended up returning the black canvas pair because the metal grommets dug into my feet - ouch!
Also, a heads up about returning items to 6pm.com. Unlike many companies that provide a return label (usually they deduct $6-8 from your return), 6pm.com does not do this. I addition, their warehouse is located in a rural area so there was an extra $3 rural delivery fee. I ended up paying $14 to return a $16 pair of sneakers - yikes! In the future, I will probably only order from 6pm.com if I know it is a pair of shoes that will work for me.
