THE NORTH FACE Thermoball Traction Mule V Winter Shoe - Insulated camp

Our review of the Thermoball Traction Mule V finds it best suited for men who want a no-fuss, warm slip-on for winter errands, campsite chores, or cabin life; the single biggest reason to buy is the combination of reliable ThermoBall Eco insulation and a cushioned, fleece-lined collar that keeps feet warm with minimal effort. The shoe prioritizes warmth and easy on-and-off wear while resisting light moisture thanks to a ripstop upper with a non-PFC DWR finish, making it a practical option when full boots would be overkill.

Key Features

• Slip-in comfort: The collapsible heel and stretchy side panels allow quick, low-effort entry while the Oso fleece-lined collar cushions the ankle for all-day comfort.
• Water-resistant durability: A ripstop upper made from 100% recycled polyester plus a non-PFC DWR finish sheds light moisture and snow to help keep feet dry on short outdoor trips.
• Superior insulation: 100% recycled ThermoBall Eco insulation maintains warmth even when conditions are damp, making these mules useful in wet-cold situations.
• Steady traction: A grippy rubber outsole with up to 20% recycled rubber offers confident footing on slick decks, icy walkways, and cold cabin floors.
• Sustainable materials: The use of recycled polyester in the upper and recycled rubber in the outsole reduces waste while delivering practical performance.

Who It's For

The Thermoball Traction Mule V is ideal for men who need a warm, easy-to-wear winter slip-on for short outdoor tasks, camping, or as a warm indoor/outdoor house shoe. It suits anyone who values insulation and quick on/off convenience over heavy-duty hiking capability.

Those who spend long days on technical trails, require full waterproof boots for deep snow, or need a very roomy fit should look elsewhere; some customers report the fit runs a bit small or snug, so people who prefer generous toe volume may prefer sizing up or a different model.

Pros & Cons
