This is the second pair of Flash Drive Platforms I bought for my girlfriend.  (Size 10)  She loves the shoes, wears them often, says they are very comfortable, easy to walk in, and we both agree they look very stylish! There are however a few negatives.  The color seems to rub off the shoe and causes the soles of her feet to turn a very very dirty black color.  The bottom sole of the shoe seems to disintegrate quickly in many areas, not just contact points.
