Over-pronation of the feet can lead to a number of problematic conditions, contributing to both foot and knee pain, shin splints, plantar fasciitis and achilles tendinopathy among others. Dance teachers and choreographers must know what to look for and know to correct it. It is reported that between 25-50% of all dance injuries are of the foot and ankle, in no small part due to alignment issues.

Ballet training in young dancers has been found to alter the normal anatomy of the foot and so allowing a student to progress with incorrect technique and alignment is liable to cause long-lasting problems. I would argue that if a dancer has issues with over-pronation, they should not be dancing on pointe until the issue is corrected. If a dancer already on pointe develops the problem, they must immediately work to correct it to avoid injury. This is yet another argument for physiological testing for the readiness of pointe work, and not judging on age alone.
A simple exercise to work on correcting slight over-pronation would be to stand in parallel, and pull your ankles into correct alignment so that that arch of your foot is not flattened but in it's natural curve. Bend your knees as far as you can go without altering the alignment of your ankles or feet, ensuring you keep your knees over your toes and hold for 10 seconds. You should still have the arch shape in your foot, and not be allowing your foot to collapse or your ankle to roll inwards. You're likely to feel a tightness in your calves as the stretch will engage the muscle at a different angle than when you plié with incorrect technique and allow your ankles to roll. Your toes should not be curled up while performing this, the small muscles of the foot should allow the toes to grip the floor without the foot rolling in; if you find your toes curling here then more general foot strengthening exercises will be required.
If you have concerns about over-pronation in your feet, find a physiotherapist who is experienced in working with dancers. While over-pronation is not necessarily a serious problem for sedentary individuals, it poses a major problem to both technique and alignment for the dancer and so finding a medical practitioner familiar with the physical demands of dance is key to correcting the problem. Dance UK have a directory of medical practitioners experienced in working with dancers which can be found here, however a web search of private physiotherapists in your local area is also likely to find physios with experience of dancers and performing artists.
If you also exercise out with dance and have problems with over-pronation, in a bid to avoid injury until you have corrected the issue ensure you have footwear that offers the correct support. I hear dancers complain a lot that they cannot run because it causes them knee pain, when the problem is often over-pronated feet and unsupportive trainers, it is a problem with alignment and not with the action of running. Go see a podiatrist, a physio and wear supportive footwear while you are working to correct the problem.
If your foot alignment is incorrect, you're opening yourself up to a lot of other things going wrong. The alignment of your foot and ankle affects the alignment of your entire lower body including your hips, which in turn affect your back and upper body. It is a fundamental problem that is far too common in dancers, both recreational and professional; the dancer, choreographer and dance teacher must all be aware of such issues and correct any problems before injury is allowed to occur.
