These are very nice, lightweight, and comfortable. Being in them for up to 15 hours a day, 6 days a week,  I appreciate all of those qualities. The vented sides keep my feet nice and cool, also resulting in frozen feet when I'm in the walk in freezer for extended periods. If I had one gripe, it would be that the non skid soles, while being very grippy, also tend to separate from the shoes after about 8 months of hard use. I have had 3 pairs, and it has happened to every pair. I obviously don't consider that a dealbreaker after paying only $20 for these shoes. If you're looking for a good pair of kitchen work shoes for a reasonable price,  I recommend these wholeheartedly.
