TNF x Skims Thermoball Traction Mule V - Cream - Size UK 4

The Thermoball Traction Mule V features a water-resistant finish, making them suitable for light snow or damp conditions. For heavy snowfall or extended exposure to wet conditions, waterproof footwear is recommended.

While they have a durable rubber outsole for traction, they are primarily designed as après-ski footwear, cabin shoes, or for light outdoor use. They are not intended for hiking or high-activity outdoor pursuits where a more secure fit and robust protection are needed.

Refer to the size chart provided by the retailer or The North Face. These are listed in UK adult foot sizes. It is recommended to measure your foot and compare it to the size guide, as the fit can be influenced by sock thickness.

Thermoball™ insulation is engineered to provide warmth comparable to down, offering excellent loft and heat retention even when wet, though traditional down may offer slightly higher warmth-to-weight ratios in extreme conditions.

The primary difference is the collaboration with SKIMS, which influences the colorways and aesthetic. Functionally, they share core features like Thermoball™ insulation and durable outsoles, but specific material accents or design details might vary between collaborations and standard models.

The heel is designed to be collapsible for easy on/off. While it may offer some minimal structure if worn partially up, it is not designed to function as a secure heel counter in that position.

Ensure socks are dry and not overly thick, which could compress insulation. Check if the insulation has been compressed by prolonged storage or heavy use. Allow them to air dry fully if damp.

Clean the rubber outsole to remove any mud, dirt, or ice buildup. Check for excessive wear on the tread pattern, which may indicate the outsole needs replacement or the shoes are nearing the end of their lifespan.

This can sometimes happen with new fleece or after cleaning. Wear them for a short period to help them soften up. Ensure they are fully dry and not exposed to excessive heat during drying.

Ensure the collapsible heel is fully pushed down. Try wearing thinner socks. The elastic side panels may become snugger over time; gentle stretching or continued wear should help.
