Best orthotics for supination: A couple of things. There is no orthotic that will make you pronate more to compensate for your supination. The only ones that you can find that might do that are custom orthotics created by a Podiatrist. However, if your issue is supination that means you most likely have a high arch as well. If you have a high arch custom orthotics will be of little help for you. What you need is an orthotic that will help make your foot more comfortable and absorb stress. Remember, pronation helps dissipate forces through your foot. Supination causes certains areas of your foot to sustain the most pressure leading to discomfort. There are some orthotics made for people with supination and high arch issues. I listed a couple below:
Aetrex High Arch Orthotics– These are not ideal for supination but if you have a high arch you may want to consider them as they provide a great deal of cushioning in high stress areas.
Powerstep Pinnacle– This would be an ideal orthotic for somebody with supination issues, but not a high arch. This orthotic has a double layer poron system to help absorb stress generated by your lack of pronation. This is about as similar to a custom orthotic as you will find on the market.
Superfeet Green Premium Insole– These orthotics are ideal for high arched feet. This orthotic has a thicker profile for people with medium to high arches. This orthotic also has some motion control as well to limit your supination. If you have a high arch and supination issues this would probably be the orthotic I would obtain.
