I’m a diabetic. I have neuropathy,edema, and vascular disease. My feet swell and go numb. I always wore a size 12 shoe. I purchased a size 12 from ortho feet and it was snug. I called them and they sent me a label to return the shoes with no problem. I reordered a size 13 wide and they are the most comfortable shoes I own. I now own three pairs of orthofeet shoes and will order from them again. I’m 68yrs old and new shoes are no longer a problem. I just go on line to the orthofeet site and order what I want. If your ever not sure or have any questions you can call them on the phone. They are all very nice and very helpful. Sincerely John Spond
