Bought this thinking it would support my walk - knees and back have old injury.  At first they were comfortable but after 2 days of walking in them, my knees and back experienced so much pain.  So I laid off walking in these for 3 days and pain subsided.  My sister-in-law walks all the time, and they injured her as well. She took them back and bought another brand - no issues.  There was another friend who had the same issues with this shoe. Buyer beware.
