I regularly develop corns and calluses. Do I need to but
custom orthotics or will any soft pad do?
The majority of custom appliances in orthotics are rip offs. If you have recurrent corns and calluses, just wear decent shoe wear and you can buy cotton pads and shoe inserts from any shoe store. These work just as good as any custom made device. Custom made orthotics devices are for people who have money to burn and like to consider themselves sophisticated.
There is a major scam in
medicine run by some foot doctors who offer bullshit orthotics for everyone who
walks into their clinic. These devices are prohibitively expensive and do
diddly squat.
