I LOVE THESE FLIO FLOPS!!  At first when I walked in these, my right foot came down a little off center.  Im no podiatrist or chiropractor, but the next day, my foot miraculously straightened out, which must have put my body in alignment.  I wear them daily, and I haven't had any hip pain since.  I was wanting sturdy flip flops, so for me, this was a BONUS beyond my expectations.
