Custom orthotic insoles tend to fall on the costlier side and may range anywhere from $200-$800. This is excluding the cost of doctor visits when you have to go in for your evaluation, design, and fitting.
There are premade orthotic insoles available, too, perfect for those who are only looking for some added comfort. Most premade orthotics are available off-the-shelf and do not cost a lot.
But if you are looking to address specific foot concerns like bunions, flat feet, complex foot deformities, alignment and balance issues, diabetes, recurring injuries, or have a higher activity level, only the custom orthotic insoles will help. They are designed with your particular concerns in mind and with your unique foot cast, so not only do they fit perfectly but also help alleviate foot and ankle issues.
