SUBU Permanent F-Line Sandals

Built with a water resistant Teflon coated nylon shell, the SUBU Permanent F-Line Sandals in Black tackle the issue of cold surfaces and damp weather ruining outdoor relaxation. These insulated slip-on shoes solve the problem of traditional slippers deteriorating on wet ground by integrating a thick four layer cushioned footbed with a rugged rubber outsole. Softly lined with a heat trapping brushed fleece interior, they deliver immediate step in warmth, shock absorption, and secure traction whether lounging at home or stepping outside into the cold.

Key Features

• Teflon treated nylon upper shields feet against light rain, dew, and accidental liquid spills.
• Four layer foam footbed construction provides exceptional shock absorption and underfoot stability.
• Insulating brushed fleece lining retains warmth directly against bare skin or socks.
• Durable synthetic rubber outsole with directional tread ensures firm grip on outdoor paths.
• Convenient slip-on profile enables quick entry while holding the foot securely.
• Includes a matching Black padded stuff sack for clean storage during travel.

At Urban Industry We Recommend These For

• Campsite evenings, morning dog walks, quick garden chores, and winter home lounging.
• Wearing barefoot for plush fleece comfort or pairing with heavy woollen socks on cold days.
• Travelers and outdoor enthusiasts seeking lightweight, water resistant slip-on footwear.

Fit & Sizing Recommendations

• Designed by the brand to run true to size with an enclosed, snug wrap across the upper foot.
• SUBU advises to select your regular shoe size for standard wear, or choose one size larger if you fall between size boundaries or plan to wear thick winter socks.
• Enclosed toe box and cushioned upper hold the foot properly aligned to prevent heel slip.

Washing & Care Instructions

• Hand wash gently in cold water using a mild soap to spot clean the nylon upper face.
• Clear dried mud or dirt from the rubber outsoles using a soft bristle brush.
• Air dry naturally at room temperature away from hot radiators or bright sunlight.
• Do not machine wash or tumble dry, as excessive heat damages the Teflon coating and foam structure.
