As soon as I saw these insoles 'in the flesh' I had misgivings, for they looked as though the offered arch support was more of a lip-service rather than anything that would be genuinely effective for me. In the event I was able to dismiss them summarily on the basis of a simple test. I had a pair of SOLE moldable insoles and a pair of Superfeet insoles to compare with, and what I was looking for was to what extent each insole limited pronation of my feet when I stood on it. Proper support for my high arches is crucial, because I have chronic plantar fasciitis AND posterior tibial tendonitis, and so reducing pronation of my feet to a minimum is extremely important.
The results of my test showed that both the SOLE and Superfeet insoles allowed only a small and probably acceptable amount of pronation (the name of the game isn't to completely immobilize the feet laterally), while a pair of Spenco orthotics reduced pronation somewhat but not enough - but these particular insoles allowed virtually full pronation, and thus were totally useless, and there was no way that I would wear them and get re-injuring my beleaguered left plantar fascia and posterior tibial tendon.
I appreciate that some reviewers have had positive experience with these insoles, but that simply shows how 'over the counter' non-custom, non-moldable insoles and orthotics are very much a hit-and-miss affair because of the differences between one person's feet and another's, even of the same nominal size. In my case, I am returning the particular insoles for a refund, and will buy further pairs of SOLE moldable or/and Superfeet insoles instead.
