I've had these shoes for 3 months now. I don't think any of these odd MBT/Shape-Up shoes are cute enough to wear out but I wear them in the house daily. I immediately noticed that they work your bum. I felt it especially when going up stairs. They are also very comfortable. I am sensitive to shoes with poor arch support and these have been very comfy and supportive. I can't think of the last pair of shoes I purchased - other than Dansko's - for which I didn't also need to buy arch supports. These shoes are great.
