DescriptionWhen you're scrambling up a rocky bluff or bounding along a riverbank, the last thing you want is gravel and grit seeping into your FiveFingers. So why not Keep Stuff Out! The KSO has a snug fit, one of our most minimal sole constructions for maximum ground feel, and a breathable, quick drying upper. The KSO also features a thin, abrasion resistant stretch polyamide and breathable stretch mesh that wraps your entire foot to do just that. A single hook-and-loop closure helps secure the fit. Non-Marking XS Trek performance rubber soles are razor-siped for sure grip.

FEATURES

• BREATHABLE MESH & NYLON UPPER: Constructed with a blend of airy polyester mesh and stretch nylon for a lightweight, well-ventilated feel. This material combination allows for airflow and flexibility during active use and gym sessions.
• MINIMALIST 3.5MM RUBBER OUTSOLE: Features a thin 3.5mm profile designed for a close-to-the-surface experience. This low-profile construction offers a flexible, lightweight alternative to traditional athletic footwear for various movements.
• VIBRAM XS TREK WITH RAZOR SIPING: Equipped with a technical XS Trek rubber outsole featuring razor-siped pods. This design is engineered for multi-directional traction on indoor gym floors and packed outdoor trails.
• ZERO-DROP & FIVE-TOE GEOMETRY: Built with a flat, zero-height platform from heel to forefoot. The signature individual toe pockets follow the foot's natural shape, allowing for independent toe separation without additional elevation or arch inserts.
• SECURE DEBRIS PROTECTION: Designed with a "Keep Stuff Out" (KSO) fit featuring a hook-and-loop strap and a snug collar. This specialized closure helps block debris during light hiking and provides a secure, locked-in fit for high-intensity movement.
