This is my first paid of MBT shoes.  I'm so excited I found them!  As others had reviewed them as running small, I ordered the next size larger and they fit perfectly. I put them on and tested out the walking....does take a little bit to get used to, but they are fantastic.  It's like walking on a cloud.  I have never had a pair of shoes make me feel this good.  I have plantar fasciitis and spinal stenosis.  I could walk all day and not get tired.  I used to have to walk with a cart or with a cane and now I don't.  I ordered another pair of MBT sandals.  I just wish they had more styles in my size.  I wear the size 8 since they run small.  Apparently a lot of women wear that size!  I have had much more expensive shoes that didn't feel this good.
