Antiaging therapies show promise in model organism research. Translation to humans is needed to address the challenges of an aging global population. Interventions to slow human aging will need to be applied to still-young individuals. However, most human aging research examines older adults, many with chronic disease. As a result, little is known about aging in young humans. We studied aging in 954 young humans, the Dunedin Study birth cohort, tracking multiple biomarkers across three time points spanning their third and fourth decades of life. We developed and validated two methods by which aging can be measured in young adults, one cross-sectional and one longitudinal. Our longitudinal mea- sure allows quantification of the pace of coordinated physiological deterioration across multiple organ systems (e.g., pulmonary, periodontal, cardiovascular, renal, hepatic, and immune function). We applied these methods to assess biological aging in young humans who had not yet developed age-related diseases. Young individuals of the same chronological age varied in their “biological aging” (declining integrity of multiple organ systems). Already, before midlife, individuals who were aging more rapidly were less physically able, showed cognitive decline and brain aging, self- reported worse health, and looked older. Measured biological aging in young adults can be used to identify causes of aging and evaluate rejuvenation therapies.
Modern Life
It begins in childhood — sitting at desks, limited play, and too much screen time.
As we grow, stillness becomes the norm. Chairs, shoes, cars, and screens replace natural movement.
By adulthood, our bodies are already adapting — in all the wrong ways. Muscles weaken, joints stiffen, and we move less without even realising it. Modern life doesn’t just reduce movement. It rewires us away from it.
Designed to Move
Our bodies were built for motion. From the ground up, everything about us is made to move — joints that bend and rotate, muscles that contract and respond, feet that adapt to uneven terrain. Movement is in our DNA.
But when we stop moving, the system breaks down. Joints stiffen. Muscles weaken. Posture collapses. And our bodies start to compensate in harmful ways — creating tension, imbalance, and pain.
Movement isn’t just natural. It’s necessary. Without it, we lose not just mobility, but function.
Reclaim Natural Movement
You don’t need a gym or hours of free time to start moving better — it begins with small choices, repeated daily. Walk during your lunch break. Take the stairs instead of the lift. Spend more time barefoot at home. Choose shoes that let your feet move naturally. These simple habits reconnect you with the way your body is meant to function.
Reclaiming natural movement isn’t about doing more — it’s about doing what’s right for your body. The more you move with intention, the more your strength, balance, and coordination return. Over time, movement becomes effortless again — not something you force, but something that flows.
MAKE THE CHANGE
Feeling stiff, unstable, or disconnected from how your body moves? If yes, this is your sign to start changing that.
Movement doesn’t have to be complicated. You just need the right tools, a bit of guidance, and a simple way to begin. That’s exactly what our Starter Bundle is designed for.
It’s everything you need to rebuild strength, stability, and mobility — starting at the feet and working your way up.
Small daily changes lead to lasting results. Your body is ready — now it’s your move.
assessing
At My Foot Function, we begin by thoroughly assessing the structure of each shoe. With our extensive knowledge of shoe manufacturing and foot function, we look beyond the surface, identifying the hidden clues that determine how a shoe will impact foot health and function. Every detail matters, from materials to design, ensuring we evaluate each shoe with precision and expertise.
testing
The testing phase starts with real-world use—we wear the shoes consistently for 14-28 days, using them exactly as intended. During this period, we analyze their effect on foot health, weight distribution, and overall comfort. To go even deeper, we cut some shoes open to examine their internal structure, revealing insights that aren't visible from the outside.
approval
Shoes that pass our testing process are MFF-approved, meeting our core principles of foot health and functionality. Approved shoes are then categorized by foot width, ensuring you find the right fit. Our goal is to be as descriptive as possible, providing a detailed breakdown of each shoe based on our rigorous assessment and testing process.
about us
Over the years, we've collaborated with some of the biggest brands in functional footwear, advising on development and education. This deep expertise allows us to test shoes at an entirely new level, focusing purely on function over style. Our mission is to provide unbiased, research-driven insights, helping you make informed choices for your foot health.
