The Flexitec Spring Steel Layer.
The patented core of the system — an ultra-thin spring steel plate that restores natural arch mechanics and supports every step from the foundation up.
Cushioning masks the problem. Support solves it.
Most insoles add foam and hope for the best. Foam compresses, flattens, and gives your arch nothing to work against. We took a different route: a thin, resilient spring steel plate that behaves the way your arch is supposed to — loading, storing, and returning energy with every step.
Three layers. One purpose.
A thin, breathable surface that moves with your foot and keeps everything quiet underfoot. You never feel a hard edge.
The patented plate is shaped with two precise wave angles — 77° and 103° — that mirror the foot's natural rolling motion. This geometry is the core of the patent: it lets the insole flex freely along its length while the width stays rigid enough to give you real stability.
A low-profile base that anchors the plate inside any shoe and keeps the whole system stable, step after step.
Your arch is a spring. We gave it one back.
With every step your arch compresses, stores energy, and releases it to propel you forward. Flat, worn-out shoes rob that spring. The steel plate reintroduces it — flexing as you land and rebounding as you push off, so more of your effort goes into moving and less is lost to the ground.
Support from the foundation up.
When the arch is supported properly, everything above it works better — ankles track straighter, knees load evenly, hips and lower back stop compensating. The plate holds your arch in its natural position without locking it rigid, so you get stability and movement at the same time.
Engineered in Germany, down to the tenth of a millimetre.
Specifications shown are indicative and to be confirmed against final production tolerances.
“Milliseconds and millimetres decided my career. This is support that respects both.”
