So far, so good
I got these to take care of shin splints and upper ankle pain when running. So far, I have not experienced any pain at all.
I was surprised that I had to trim them, but pleasantly so since at size 15 I usually have to deal with empty space instead of a proper fit.
I do think that the arch may be a little too close to the heel, but that hasn't caused any trouble.
