I love these things. My daughter (who's in the medical field)turned me on to these. She, as do I, has a need for arch support because they're so high. She also knew my arches has been falling due to age (I'm in my late forties)and I need inserts in my work shoes. She's been wearing her pair since last fall (2006) and picked me up some of the Croc "glides?" in March.
I liked them so much I ordered these Caymans for myself. Amazing support for "difficult" feet. I wear them whenever I'm not in my work shoes. I may look somewhat foolish (they're marketed at a much lower age bracket than myself), but I'm comfortable so I don't care.
These clogs are a closed cell resin which is anti-microbial by nature and resists odor, making these perfect barefoot shoes. A combination of material and design makes the shoe slip resistant. Strategically placed ventilation holes allow water, sand and air to travel through the footwear. Heel strap can be rolled forward for a slip on clog shoe or keep it back for a heel strap. Arch support is built in, making these all day shoes. Non marking outsole.
