Primal RunAmocs shown to increase foot muscle growth in kids

A 2023 scientific research study of elementary aged school children wearing Softstar shoes was conducted by scientists from the University of Sydney, Western Sydney University, and the University of South Florida. The study looked at children aged 8-12 attending a private school in Sydney where black dress shoes were required by uniform. The researchers wanted the most barefoot-like shoes which would meet the approval of the school dress code. They found that our Primal RunAmocs met this criteria. Based on the Minimal Index scale, the Primal RunAmocs were given a rating of 94%, where 100% represents the highest degree of minimalism.

The study found that minimalist shoes increase foot muscle growth in kids. Learn more about this and other kids barefoot research on our Growing Feet page.
