My podiatrist recommended I get these and after trying to wear them for the last three months I've said no more. I have chronic pain from plantars fasciitis and these don't help at all. I even asked the manufacturer why the arch placement is so far back on the foot and they said its normal. I don't think it is. I spent way too much on something that doesn't work for me but I can't send back because right after I got them I had to trim them for my shoes. Waste of time.
