I was having constant pain in my knees for months, then i went to the doctor and he told me the way my arches are built cause my knees to tend inwards. He also said i could buy a pair of athletic shoes designed for people like me or i could just have custom orthotic insoles made. I know doing things like running and squatting can cause damage if your knees are pronating. can these arche supports endure training enough to keep my legs healthy. Does anyone else have this problem with their feet or does anyone know what i should do with this problem, cause i could use your help cause im lost.
