Shoes can change how you walk, but 'fixing biomechanics' is a stretch.

Other research found that special shoes helped people with polio walk better and balance better, so the right shoes can genuinely improve movement for some people. But another study showed that shoes alter how your feet and walking work without proving those changes are good or corrective. So the idea that shoes 'fix' biomechanics is overstated—they can change it, but whether that's a fix depends on the person and the problem. The specific claim about 26 bones and dozens of muscles is a basic anatomical fact, but we didn't find studies in our databases to evaluate it directly.
