I love leather shoes, but they can be a bit too warm in the summertime.  I need a closed toed shoe with good support in many situations.  This is almost as airy as my open toed sandals, with all the protection of a closed in shoe.  They are cute and feminine.  The adjustability of the Velcro closure is a big bonus.  They work well with or without thin socks, though I plan on mostly wearing them with no socks.  The foot support is awesome, with just the right amount of cushion.  I will take support over cushion any day, but cushion is a great bonus.  These will look good with jeans, and great with light slacks or a long skirt.  If you can wear shorts, it's cuter than and as functional as a sneaker.  I have a narrow shallow foot, and these fit perfectly.  If your foot is more toward a normal width or a bit plumper, you may want to go with a wide.
Peltz, the seller was great.  The shoes arrived a day ahead of schedule.
