A report in the journal Arthritis Care and Research says flatter shoes are easier on the knees than clogs or walking shoes.
The loading of a person's weight on to the knee joint is thought to be a key factor in the development of arthritis. In a previous study researchers at Rush Medical College found that people walking barefoot had less loading on their knees.
To investigate further they analyzed what was happening with shoes on. The flat flexible shoes won out, but researchers are not ready to make any blanket recommendations on the best footwear for osteoarthritis.
