Got these because had bought similar Sbicca a few years ago and they were wearing out.  Think I love this newer (different) design more than the other.  Highly recommend.
EDIT 04/29/13.  Don't get them wet.  I did and now have a rash on my feet every time I TRY TO wear them.  Must be something in the dye or glue. I have tried to ask the manufacturer But, NO ANSWER.  Have tried Taping the under side of strap, ointments,--you name it.  Nothing works.  My dermatologist said throw them away.  I can not wear them but I still like the look and feel so am still giving 2 stars.
