My husband and I own our own business. We are a seasonal business so from February thru October we are extremely busy. I am on my feet 12 to 15 hours a day. I have tried many other top rated, name brand shoes, and these are the only shoes I have ever worn that keep my legs and feet from being tired at the end of the day. I also work out 4 times a week and I definitely have noticed a difference in my derriere. So has my husband! I have been wearing these shoes for 3 years and I plan to continue!
