Sanuk delivers again.  This is my 7th Sanuk purchase this year (yes, it's only April if that tells you anything), and I am still as impressed as ever.  This is a HIGH quality flip flop.  With the yoga mat sole, the fabric upper, this is a sturdy, well made shoe.  What is especially nice is they have some sort of support built into the back of the shoe, so there is no way it will flatten from the weight of walking on it, and it will retain it's shape.  Most of the time with wedge sandals, it flattens or the structure is compromised once you wear it, but they've designed this so that is prevented.  It is a tiny wedge, which is great for me as I'm already 6ft tall, but they give your leg a nice shape and the shoe looks more dressy than a regular flip flop.  I could easily wear it to work and wouldn't have any issues with it not meeting business casual with a dress, skirt or capris.  Great price, great buy, great delivery, great shoe.  Praise Sanuk!
