SUBU Permanent F-Line Sandals

Designed with a durable water resistant Teflon coated nylon upper, the SUBU Permanent F-Line Sandals in Matcha eliminate the inconvenience of cold, damp feet during quick outdoor trips or campsite relaxing. These insulated slip-on shoes solve the problem of traditional winter slippers lacking outdoor durability by combining a thick four layer cushioned footbed with a rugged rubber outsole. Lined with a soft brushed fleece interior, they offer immediate warmth, shock absorption, and reliable traction for indoor lounging or outdoor errands in chilly weather.

Key Features

• Teflon coated nylon upper provides water repellency and protection against light spills and moisture.
• Four layer cushioned sole structure delivers exceptional footbed support and shock absorption.
• Plush brushed fleece lining traps heat for immediate warmth against cold floors or wet grass.
• Durable rubber outsole features multi directional tread for secure traction on slippery surfaces.
• Convenient slip-on design allows fast on and off wear without sacrificing heel containment.
• Matching padded storage bag included for easy travel and compact packing inside a backpack.

At Urban Industry We Recommend These For

• Campsite lounging, morning dog walks, quick garden errands, and indoor winter relaxation.
• Wearing comfortably barefoot or pairing alongside thick woollen socks for maximum thermal comfort.
• Travelers and outdoor enthusiasts needing packable, weather resistant footwear for cold environments.

Fit & Sizing Recommendations

• Designed by the brand to run true to size with an enclosed snug fit across the top of the foot.
• SUBU advises opting for your standard shoe size for a secure fit, or choosing one size larger if you intend to wear heavy winter socks regularly.
• Padded upper wrap gently holds the foot in place to prevent heel slip while walking.

Washing & Care Instructions

• Hand wash gently using cold water and a mild detergent to clean dirt from the nylon face.
• Use a soft bristle brush to wipe away mud or debris from the rubber soles.
• Air dry naturally at room temperature away from direct radiators or hot sunlight.
• Do not machine wash or tumble dry, as excessive heat damages the Teflon coating and foam layers.

SUBU Permanent F-Line Sandals - Our FAQs
