Vivobarefoot Primus Lite IV All‑Weather Men’s Obsidian
Introducing the Vivobarefoot Primus Lite IV All‑Weather in Obsidian—a barefoot trainer engineered for unpredictable conditions. Waterproof, versatile, and purely minimalist.
Unmatched All‑Weather Performance
- Waterproof Barrier: High-spec membrane seals out rain & snow, perfect for wet weather training.
- Barefoot Feel: Bare 4 mm thin sole with a wide, foot-shaped toe box for ground connection.
- Durable & Lightweight: Fewer materials, responsible build—just 280 g (per shoe, UK 9).
- Eco Materials: Upper made from recycled plastics; fully vinyl- and vegan-free.
Built for Functional Fitness & Movement
- Active and grippy outsole—solid traction on wet, urban, and trail surfaces.
- Removable 3mm insole for versatile cushioning preferences.
- Lightweight breathable upper—manages moisture and heat even in wet conditions.
Fit & Sizing Guidance
Foot-shaped design encourages natural toe splay. If between sizes, size up for added comfort without heel slippage.
Care & Maintenance
Wipe clean with damp cloth and mild soap. Avoid machine washing; air dry only.
Why the Primus Lite IV?
The perfect fusion of barefoot freedom and weather resistance—committed to natural movement, durability, and planet-safe materials. Stay agile, grounded, and prepared for any weather.
Get the Right Fit the First Time
We want to make sure you pick the perfect size when ordering online. That’s why we’ve created clear, easy-to-use size charts for every Vivobarefoot product.
Not the right fit? Changed your mind? No worries. Return your gear in unused condition within 365 days for a full refund or store credit — no fuss, no pressure.
Our Size Guide is here to help! Vivobarefoot fit 'big' deliberately – we call this ‘the rule of thumb’. Your toes need wiggle room! This is especially important for running. If you can fit your thumb in-between the end of your toe and the front of the shoe, you’ve more than likely found your ideal size.
**After some time with Vivobarefoot shoes, your shoe size may need to increase, as your toes splay out more naturally.**
