I spent a day in such a shoe store observing the operation. You insist on the necessity of 'arch cookies,' 'cuboids,' 'metatarsal supports,' and so on-yet from the continuous complaints of customers, you know that these supports are of no help to the feet. Besides, I always instruct them to do certain exercises. They never do them. That usually shuts them up.
Bare feet can go safely on hard surfaces .
This kind of alarmist statement really puzzles us. It goes completely against our own experience and that of a good number of medical researchers. An average day of walking, for example, brings a force equal to several hundred tons to bear on the feet. This helps explain why your feet are more subject to injury than any other part of your body. Weight is not cumulative in this way.
