Those shoes are really good, especially for my situation of having problems with the right sole for some unknown reasons. Now, I wear barefoot shoes for different occasions, such as walking, doing sports exercises, etc. Before that, I had difficulties wearing some traditional sports shoes because of problems with my right sole. This new experience changed my mindset. I thought I was unable to wear sports shoes of any kind. I hope the products can mitigate the level of back pain as well.
