I won't bad mouth the company, but I am on my feet 6-8 hours a day and my feet hurt afterwards, I also have heel spurs. A friend told me about these and gave me a flyer and it sounded really good. I looked online and decided to try the GDefy Extora ll because it said they helped with ALL foot pain NOT! I expected to feel the heel kind of bounce (I guess) since there was a spring, I expected not to feel my feet hit the floor; but that's definitely not what I experienced! I wore these today for 6 hours, by the time I got home, my feet and especially my heels were hurting. They are heavy and feel like Herman Munster shoes, they made me sound like I was stomping even when I tried to walk softly. The upper "leather" is so stiff that it rubbed my ankles and caused them to get sore and swell, my feet feel very tired after wearing them for so long. I would not recommend this brand, but the others might be ok. I however have decided not to bother trying another expensive pair because I don't want to go through this again; I am returning them for a refund and sincerely hope I don't have all the troubles others have had with theirs. I am glad to read that there are those who have had great results with their chosen shoes! I guess we just never know until we try them right? :)
