Ballet flat shoes – those thin-heeled lightweight slip-on shoes – are making a fashion comeback. And it’s not hard to see why: they’re versatile, easy to wear, soft, flexible and often worn by celebrities.
We have often been warned of the dangers of high-heeled shoes, so you might think ballet flats are problem-free.
When you look at the research, however, a complicated picture emerges. There’s no definitive evidence to show ballet flats are generally harmful to foot health in the long-term. But ill-fitting ballet flats can be a problem.
An estimated 70 per cent of the population are wearing ill-fitting shoes. This mismatch between foot and shoe shape can increase foot pain, reduce stability, and can mean more blisters, corns and calluses. And habitual wearing of tight shoes has been associated with bone changes in the toes and feet over time.
Many flats feature a shallow and narrow toe box (the part of the shoe where the toes go). A too-small toe box often doesn’t align with the shape of a foot and ends up squishing the toes. It can also increase pressure on top of and under the foot, and restrict the movement of the forefoot during walking.
But a too-big toe box is also a problem. Too much foot movement within the shoe can cause pressure and friction on the skin, which can also lead to calluses, corns, blisters, and wounds.
A poorly fitting toe box can also cause micro trauma to toenails which, ultimately, can change their look and thickness.
So if you’re wearing flats, make sure you choose a shoe with the right-sized toe box.
