The first studies on the biomechanical effects of arch support and gradient compression began to show significant promise for treating chronic foot ailments in the late 20th century.
The research that has followed has produced fascinating evidence of a powerful and positive shift in the structural alignment of the foot, the electrodynamics of blood flow, and a boost to self-healing and tissue recovery mechanisms within the plantar fascia.
We believe that the Norvo® Foot Sleeve's Tri-Vector Gradient Compression™ allows a rhythmic pumping effect that drives fresh, oxygenated blood deep into the heel. We know that inflammation is exacerbated by poor hemodynamics and repetitive micro-tears. By physically locking the arch in its optimal position (Kinetic Arch Suspension™), tension on the plantar fascia is neutralized, allowing the "brittle rubber band" to rest, flush out inflammatory waste, and rehydrate.
In the clinical studies, as well as testimonials from thousands of customers who have worn Norvo® Sleeves, we have consistent evidence of people whose morning "first step" pain has been significantly reduced. Such reduction of pain is evidence that inflammation is reduced, the workload is offloaded from damaged tissue, and youthful elasticity is being restored to the foot.
