Underpronation or underpronators is a term used by runners when it comes to a foot that supinates more then it pronates. However, the conditions that can result from this problem include metatarsalgia, plantar fasciitis or Achilles Tendonitis and many more. The treatment for underpronation is orthotics or insoles for the shoe. But what kind of orthotic should a person who is underpronating get?
The ideal orthotic for an under pronator is a custom orthotic from a Podiatrist. The Podiatrist takes a cast of your foot and then sends it to an orthotic lab who makes an orthotic specifically designed for your foot. This can run upwards of $600 a pair but on occasion is covered by insurance.
If that is not an option you can try an inexpensive version of orthotics: over the counter orthotics. There are many different over the counter orthotics available. What you want to look for in an orthotic for a underpronator, is really what the orthotic does not have. You do not want an orthotic with a deep heel cup; you do not need control. If you are an underpronator essentially your foot already has a great deal of control. One of the most important things is padding and cushioning. Because you are an underpronator your foot is taking a great deal of force because it does not pronate enough to dissipate the force. You also want mild to moderate arch support that contours to the arch of your foot. Here are a couple examples of orthotics I would recommend for underpronators:
Spenco Polysorb Total Support– These orthotics allow the freedom an underpronator desires, while also providing the padding via their Spencore material to add a cushioning layer to absorb the force and shock from gait.
Superfeet Premium Insoles– This full length orthotic is similar to the Spenco orthotic above though it does not provide as much padding in the area. This orthotic would be superior for a runner than the Spenco listed above as it has more performance attributes.
New Balance Insoles Supporting Cushioning Insoles– This orthotic provides the most comfort and padding available in an orthotic on the market, which I think makes it the best choice for an underpronator. However, if I was a runner then I would probably choose the Superfeet Premium Insole.
