Modern shoes forgot how humans move.
Ultra-thin engineered support that restores what modern shoes left behind — inside the shoes you already love.
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.
Keep the shoes you love. Upgrade every pair.
Worn by people who move.
“As I'm training for an triathlon I'm moving a lot. Especially during my runs fatigue would kick in fast. With the flexitec soles I can honestly say I'm fatiguing less during my runs. I'd buy it 3 more times, absolutely worth the money.”
“I've been using the SOLE insoles for a while now and I'm very satisfied. They give more support and stability without feeling hard. My shoes stay comfortable and my feet feel less tired. The insoles fit easily and feel high quality. Fast delivery and neatly packaged.”

Invisible technology. Visible difference.
Spring steel core, natural flex, ultra-thin profile. Slide it into any shoe and feel the foundation change.
“Support you stop thinking about — that's the whole point.”
Backed by alpine skiing legend Felix Neureuther, Sole is built to the standard of people who move for a living — and refined for everyone who just wants to move better.
