I really like the style of these shoes and have bought similar styles but these have more sole padding than any other type I've bought before.  These are by far the first and only shoes I've ever owned that slip on carpet.  Yes, you read that right, they are so slick on the bottom it's unbelievable.  Im pretty sure they are approved for bowling.  Head others reviews on the traction issue.  Overall I feel like these are too expensive for what you get.  I know it's for a good cause but dang, slipping on carpet?!  Come on!!
