I work at a post office and I'm on my feet all day, both standing and walking. Although I own several pairs of clogs, this is the only pair I can wear all day and not come home with horrible foot and leg pain. I do not find them heavy to wear at all. They have excellent arch support and the sole is just right amount of cushy. Although they feel loose on my feet - the heel slips as I'm told they're supposed to - I've never felt they're going to fly off. By the end of the day, having them be a little loose is a good thing. I have another pair of Klogs Naples in black suede (a discontinued style) and oddly enough, they don't feel and fit as good as my Black Shimmer pair. Another plus is they cordinate with my uniform of either black, navy or grey pants. The "oil slick" finish isn't too shiny or too matte and the leather definitely seems to be holding up well - not showing scuffs marks -  after 3 months of nearly constant wear. I get lots of compliments on these shoes and recommend them to my co-workers - they are truly THE BEST!
