I bought these in my regular size and found the Left shoe irritated my big toe which is a litle distorted. But no problem - just used Happy Returns for the easiest return ever and got a half size larger. Even my doctor complemented me on these shoes and agreed that the higher heel did make a change in my posture (to more errect), and lessened former knee and R leg pain from my spinal stenosis. My closet is full with 6 pair of Bzees shoes and no need to look at another brand. I have spread the word to my friends about the perfect comfort, washability and great style of Bzees shoes. Open the box, try them on, and walk around all day in comfort. No sore spots, no discomfort from the first step - and later on throw them in the washer, air dry and they look just like new. Amazing!
