My OH uses a hippy parenting forum and serveral people on there have tried suprisingly cheap 5 fingers from a popular internet auction site that rhyms with d-day. The conclusion seems to be they are a bit crap and always either have really bad stiching and fall apart or rub badly. Hope your's work out better for you.
I'm sure vibrams are great, but I don't think they are a good value for money product, but the same goes IMHO for most branded running shoes be they barefoot, minimalsit or supper squishy with springs and flashing lights.
You know all those pictures of Adam and Eve where they have belly button? Think about it..................... take as long as you need........................
