INCREDIBLE!  I own seven pair of MBT shoes. Don't be fooled!  If you see some online and the site says, "all sizes, colors, styles for $89.00", they are COUNTERFEIT!  I had no clue these shoes were being copied by companies all over Asia.  The box is the same, the serial numbers and style of shoes are the same, but they are CRAPPY MADE.  This pair is REAL and I'm thrilled.  I bought one pair of fakes a few years ago and immediately knew the difference...the pain in my hip came back when I put them on.  If you don't have a medical issue and you just want shoes that have rocker bottoms, Sketchers MAY be okay, but keep in mind they ARE NOT ALIKE.  There is NO comparison to the way these shoes are made and all the others on the market that have rocker bottoms.  Because this brand of shoe has taken back and hip pain away, I'll never wear anything else.  YES, they are expensive, but if you go to the MBT homepage there is a list of legitimate dealers and stores.  I have been able to find REAL MBT shoes on sale. If you have back or hip pain, try them!
