FOOT HEALTH - it's not a matter of heel height that matters...
Flats with no arch support can be just as damaging as ultra-highs. In fact poor fit to one's unique foot shape, designs which force feet into unnatural positions, wrong size, no/poor arch support. unstable heels (regardless of height) are among common causes for foot problems.
"...with the shops full of practical-looking loafers, brogues and moccasins, you might think physiotherapists and podiatrists across the country would be panicking that they’d be out of a job.
In fact, they’re expecting to be busier than ever. Podiatrist Beverley Ashdown says: ‘There’s been so much publicity about the damage high heels can cause to our feet, knees and backs, we forget that flat shoes — particularly ones that offer little or no support to the foot — can cause just as many serious foot and postural problems.’+Jim Philips
while you explore the topic of footwear, please do not perpetuate the myth that the height of heels is the singular cause for poor health in feet. It is a gross generalization to suggest any type of heel height is a problem. It is also irresponsible since readers may be influenced by your post and opt for equally damaging flats with no arch support instead and to make the switch overnight (a gradual approach minimizes the damage risk from change.)
Selecting optimal footwear is not a straightforward exercise because of the many factors to keep in mind, but imo there is an acid test - are your feet absolutely comfortable in the shoes and will be at the end of a long active day wearing them. (I've had runners I had to get rid of because they did not meet my test but they were ideal for others.)
And, in 2015 women can find attractive, stylish shoes which can meet the happy feet test for themselves. Wearing ugly shoes is not a requirement for maintaining healthy feet.
