I just read about these new flip flops (sandals) that were introduced in May, the FitFlops.  Seems like these are like the Crocs, another hard to find item?  Out of stock everywhere. 

This shoe has a claim that with every step, you will tone your legs.  It is like walking barefoot in sand.  And believe me, I was at the beach a few weeks ago, walking in very fine sand for an hour, boy, that was some workout. 
These are the rage in the UK, just arriving in the US, the #2 most sought after shoe. The word is that stock will be available in the US at Blissworld.com in early July. You can go there and preorder.
