I work in the food service industry and I am on my feet, on concrete, for long hours.

The first day that I wore these to work, I noticed that they are NOT AS SLIP-RESISTANT as I was really hoping for.  They are "ok" in this area, but in my line of work, I like shoes that are VERY slip-resistant, and not just "ok."  One slip is all that it takes to for an injury to occur!

Also - they do not offer the great arch-support that I was hoping for.
This is a big issue with me, because poor arch and heel support, for me, means aching feet!

I also noticed after wearing them for a day that my feet get very hot, as there are no holes or vents for circulation to pass; the material that surrounds the foot, with no circulation vents, is just plain HOT.

They look good though!  :)
