How We Got Started

PRIMFIT was born from a blend of observation, innovation, and the drive to make a difference. Our co-founder, Dr. Arik Poremba, noticed the significant benefits of dynamic movement on unstable surfaces during his physical therapy sessions. Yet, to achieve this effect, he found himself filling his clinic with foam mats, creating an environment that was effective, but space-consuming and not easily replicable outside the clinic.

A thought sparked: what if the instability could be made portable? What if it could be integrated into something as commonplace as footwear? From this idea, PRIMFIT was born.

Today, PRIMFIT continues to empower individuals to enhance their mobility, elevate their performance, and lead more active, fulfilling lives. With PRIMFIT, we're not just changing how you train; we're improving the way you move
