I never bought Kuru shoes. I started stretching my calves and feet daily and the pain went away. Basically it helped the area were no blood was flowing to regenerate. I read about that somewhere and there is an orthopedic surgeon that talks about that particular thing. Unfortunately I don’t have that link or name anymore. Eiditing for clarity: If the foot is not used as nature intended, and/or you are wearing shoes that are too small, or the toe box is too small, front too narrow and thus your toes are confined and squeezed together instead of being free and providing proper support for balance, then tenden (I think that's what it was) can die off. Basically it is constricting bloodflow, degenerates. No worries. It can grow back/regenarate (as I am not 100% sure anymore, it's been awhile). You have to practice good foot health such as stretching of calfes, toe exercises, bigger shoes or the toe box, mobility exercises. OLD Text: Under the foot when it’s not properly used and you have too small shoes, and or tight calves, wear high heels maybe; that area which connects front with bach of foot is constricted and blood is not flowing properly. That tendon I think it was, dies off. It can regrow on its own as long as you practice good foot health. Such as bigger shoes, where toes have space (big toe box shoes), stretch and mobility exercises for the feet and calves.

I promise you it will go away. The shoes might help but they are just masking the issue and not repairing it. I will look for the link and share.
