I did the Foot Levelers orthotics thing some years back. I still have them and have used them constantly with complete satisfaction. They are a great combination of matching paperweights and conversation starters. I put them right up there with Popiel’s Pocket Fisherman (although I hear you can really catch fish with the PF. They fit in any of my shoes, running, cycling, walking, sleeping, you name it. They also did work fairly well in my ski boots.
The money that you will spend is worth it, because it is cheaper than surgery, and less painful than the injections ,which didn’t help. The stabilizing orthotics did help me. They were not uncomfortable and I hardly knew they were in my shoes. They do raise the foot at the heel ,but it caused no problem for me.
I tried every sort of expensive and inexpensive shoe that was available at the time, some with significant padding that included gel, air, or liquid under the forefoot *and* the heel areas. Basically there was no difference. If you’re going for an insole rather than a custom orthotic the best one around is made by Foot Levelers. They make special inserts for different shoes and different sports. I use their Casual Intense Comfort in my casual shoes.
I would also not be able to race and train without my stabilizing orthotics. I train and race with my orthotics and have no problem with them sliding around once my foot becomes accustomed to them. With the heel cupped firmly, and the shoe laced and pulled up tight, my foot stays firmly in the stabilizing orthotics and the orthotic rides with my heel. They are tremendously useful and highly recommend them.
