WHY VIVOBAREFOOT IS DIFFERENT
Vivobarefoot shoes are designed to let your feet move naturally. With a wide toe box, thin flexible sole, and zero-drop platform, they allow your feet to function the way they were designed to. Traditional shoes often add cushioning and structure that can reduce natural movement and sensory feedback.
| Feature | Vivobarefoot | Traditional Shoes |
|---|---|---|
| Toe Box | Wide and foot-shaped for natural toe splay | Narrow and tapered |
| Sole | Thin and flexible for ground feel | Thick and cushioned |
| Heel Drop | Zero drop for natural posture | Raised heel alters posture |
| Movement | Encourages natural foot strength and mobility | Supports and restricts natural movement |
| Purpose | Designed to reconnect you with natural movement | Designed mainly for cushioning and control |
