I have really high arches, and regular ballet flats just don't work for me.  I need a more supportive shoe, but I also wanted something that looked somewhat trendy and one that could stand up to moisture, was non-slip, and comfortable.  These do the job just fine.  I wear several other styles of Crocs (I have the Kaydee in leopard print, as well as Capri style flip flops; also, the Mammoth for winter time) and they are perfect for Florida living.  This style can get a bit warm if worn without socks, but the comfort and cuteness factor make up for that.  I am very happy with this purchase - in fact, I plan to get a pair in Espresso also!
