Here is a dancer's pad made of insole material cut up. You can purchase from www.mooremedical.com 1/8th inch adhesive felt, with emphasis on the adhesive part. In this way you can add dancer's padding to off weight the big toe joint area in any shoe, or on any insert. The goal is to try to get less pressure on the sesamoid as you roll through you foot.
Dr Blake's commment: Yes!!! Maybe with a small dancer's pad for good luck? When I watch people walk in heels (in San Francisco it is both sexes LOL), you can see that some heels work better than flats at getting the weight to the lateral side of the foot (4/5 toes). You have to try on many of the same heel height and see where the pressures go. Good luck. Rich
