These are A-line inserts that run $60-$75 a pair. This is for a size 10 in women’s. Helps with plantar fasciitis, knee pain, back pain, hip pain, whatever your alignment issue is. We all know that different inserts work for different people, they are not all the same, I tried these and they did not work for me. My loss, your gain! Please see website and you tube for more info on how to break these in. (These are new and not used but one time).
