I wear Ryn shoes. They have more stability in the side-to-side axis while having the full rocker front-to-back. They continue to be made in Korea, as MBT's used to be. I think they are a superior shoe to MBT's. I'm 59 with bone spurs in my feet and arthritis in my knees and, wearing these exclusively on the street, have had no problems with injury. I do worry when I have to run for a bus through.
I am looking for a barefoot shoe though. I still experience some pain with bone spurs wearing Ryn's, but no pain going about the house barefoot. That's probably because I'm not walking distances inside, but I think it's worth testing. Living and working in a city don't give me much terrain for true barefoot walking sadly.
Esther - I followed your advice and read the material on MBTs originally in the Oct 2007 newsletter.
My issue is as follows: The phylangeal metatarsal joint in my right great toe is very deteriorated/arthritic. I have been wearing rocker bottom shoes (now Ryn) for years, to avoid repetitive use of the joint. Each night, I do certain, controlled movements to use the same joint, safely.
But I have been using the shoes in a lazy manner. I have not been touching down at the back of the heal, but rather towards the center of the sole. It seems that if I focus on using the rocker bottom shoes properly, I will be using my buttocks & leg muscles, while protecting my injured joint. Please comment. Thank you very much.
