I bought the VFF and ... I like the feeling of them, but my toes just aren't happy. I can only wear them for about an hour before my feet start cramping (maybe from my toes not being happy about being separated from their buddies). I only wore them maybe 10-15 times... bummer. A lot of $$ for something that was a washout for me. If anyone wants slightly used VFF (I will look up what style and size), PM me... (I can throw them in the wash before I send them to you and I don't have any foot funk...). Maybe I'll try those birthday shoes. Also, has anyone worn Sanuk's? I LUUURRRRVVVVEEE them! They are sandles with a shoe upper - made by surfers, and I can wear them working in a lab! Have I mentioned that I love them? They truly are flip flops with a slightly more presentable look... I consider them my new barefoot shoes.
