SUBU Permanent F-Line Sandals

To keep feet warm, dry, and protected on cool campsite mornings or during quick outdoor errands, the SUBU Permanent F-Line Sandals in Mountain Khaki feature a water resistant Teflon treated nylon upper. These insulated slip-on shoes solve the problem of cold surfaces causing discomfort by combining a plush, heat trapping brushed fleece lining with a thick four layer cushioned footbed. Built with a non slip rubber outsole and accompanied by a matching travel sack, they offer instant step in warmth, shock absorption, and steady traction across smooth indoor floors, gravel paths, and damp grass.

• Four layer foam footbed construction absorbs impact and supports feet on hard surfaces.
• Plush brushed fleece lining holds thermal heat close to bare skin or socks.
• Durable synthetic rubber outsole with directional tread ensures stability on outdoor paths.
• Enclosed toe slip-on profile allows fast step in access while keeping feet secure.
• Includes a matching Mountain Khaki padded stuff sack for clean storage during travel.

At Urban Industry We Recommend These For

• Campsite evening lounging, morning coffee runs, garden errands, and cold tile home wear.
• Wearing barefoot for immediate fleece skin comfort or pairing with heavy woollen socks in cold weather.
• Outdoor enthusiasts and travelers seeking lightweight, packable slip-on footwear for damp ground.

Fit & Sizing Recommendations

• Designed by the brand to run true to size with an enclosed, snug wrap across the upper foot.
• SUBU recommends to select your standard shoe size for regular wear, or choose one size larger if you sit between size ranges or prefer wearing thick socks.
• Cushioned upper wrap keeps your foot properly aligned to prevent heel slippage while walking.

Washing & Care Instructions

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