To keep feet warm, dry, and supported during chilly outdoor errands or relaxing around camp, the SUBU Permanent F-Line Sandals in Dark Brown combine a weather resistant Teflon coated nylon upper with a plush, heat trapping brushed fleece interior. These insulated slip-on shoes solve the issue of flimsy winter slippers wearing out on wet grass or cold concrete by utilising a thick four layer cushioned footbed and a durable synthetic rubber outsole. Complete with a packable matching nylon bag, they deliver instant step in comfort, shock absorption, and reliable traction for indoor and outdoor wear.

Key Features

• Water resistant Teflon coated nylon shell shields feet against damp grass and light spills.
• Four layer foam footbed construction absorbs impact and supports the foot arch.
• Soft brushed fleece lining provides thermal insulation directly against bare skin or socks.
• Heavy duty synthetic rubber outsole features multi directional tread for secure grip on outdoor paths.
• Enclosed toe slip-on design allows fast, effortless entry while holding the heel firmly in place.
• Comes complete with a color matching padded stuff sack for convenient travel packing.

At Urban Industry We Recommend These For

• Campsite evening wear, morning dog walking, garden chores, and indoor winter lounging.
• Wearing barefoot for immediate plush warmth or pairing with thick woollen socks in freezing conditions.
• Travelers wanting compact, insulated slip-on footwear that handles damp outdoor ground.

Fit & Sizing Recommendations

• Official sizing from the brand recommends a true to size fit with a snug wrap across the upper foot.
• SUBU advises to select your regular shoe size for standard wear, or size up if you fall between size brackets or plan to wear thick outdoor socks.
• Padded upper lining prevents friction and keeps the sandal positioned correctly while walking.

Washing & Care Instructions

• Hand wash gently in cold water using a mild soap to clean the nylon upper.
• Scrub the rubber outsoles with a soft bristle brush to clear dried mud or dirt.
• Air dry naturally at room temperature away from hot radiators or direct sunlight.
• Do not machine wash or tumble dry, as high temperatures ruin the Teflon layer and foam cushioning.
