Rrat's Y-Mountain

The most rugged barefoot sandal for the mountains

The Y‑Mountain by Rrat’s is built for those who never stop. With a firm structure, 17 mm Vibram sole and vegan construction, it's the toughest barefoot sandal in the collection.

Ideal for mountain routes, technical trails or long hikes where you need maximum security without losing ground feel.

Main advantages

Thanks to its slightly thicker sole, the Y‑Mountain offers extra protection against rocks, roots and rough terrain. Yet it still delivers a reactive, natural step — with no artificial cushioning.

The Y‑strap system secures the foot without pressure or rubbing. Perfect for those who walk for hours without thinking about their footwear.

Recommended use

Designed for mountains, thru-hikes, technical trails or situations where a lighter sandal is not enough. Also a great option for people who need more underfoot protection due to body weight, experience level or typical terrain.

Real reviews

People who’ve tried the Y‑Mountain praise its stability, performance on slopes and the confidence it provides with every step. It’s not just another sandal — it’s a solid step toward natural movement, even in tough conditions.

Care and maintenance

Wash by hand and let air dry. Avoid direct sunlight or heat sources. No special treatment needed: it’s built to last and to follow you where others won’t.
