THE NORTH FACE Thermoball Traction Mule V Winter Shoe - Warm Men's

Our review of the Thermoball Traction Mule V finds it best suited for men who want a no-fuss, insulated winter slip-on that works indoors and around camp. The single biggest reason to buy is its balance of thoughtful insulation and easy on/off convenience: ThermoBall Eco insulation delivers real warmth even in damp conditions while the collapsible heel and stretchy side panels make slipping them on quick. These are not a heavy-duty mountaineering boot but a dependable, everyday winter shoe for cold, mixed-weather use.

Key Features

• Slip-in comfort: A collapsible heel, stretchy side panels and a soft Oso fleece-lined collar combine to make entry and wear comfortable and low-effort for quick trips outside or lounging indoors.
• Superior insulation: ThermoBall Eco insulation made from 100% recycled polyester retains warmth even if the outer fabric gets wet, which helps on damp mornings and around melting snow.
• Water-resistant durability: The ripstop upper is made from 100% recycled polyester with a non-PFC DWR finish to shed light moisture and snow and extend wear life in winter conditions.
• Steady traction: A grippy rubber outsole with up to 20% recycled rubber offers stable footing on slick decks, icy steps and cold cabin floors.
• Sustainable elements: Recycled materials in the upper, insulation and outsole reduce waste while still delivering practical performance for everyday cold-weather use.

Who It's For

The Thermoball Traction Mule V is ideal for men who need a warm, easy-to-wear winter shoe for casual outdoor tasks, camp chores, and living space to trailhead transitions. It works well for commuters who step from car to office, campers who want a lightweight warm option around camp, and anyone who values insulated slip-ons for quick outings.

Those looking for a rugged hiking boot, full waterproof protection for deep snow, or a precise athletic fit should look elsewhere. Also, buyers who prefer roomy toeboxes should try them on first: some users find the fit snug and others praise the fit, so sizing attention is recommended.
