Outdoor Research Women's Footwear

Frequently Asked Questions

• What materials and construction make the Outdoor Research Women's Tundra Trax Slip-On Booties suitable for cold weather?

  The Tundra Trax uses a 100% recycled Pertex Quantum Eco shell (53% recycled polyester/47% polyester double ripstop) that’s water‑resistant, wind‑resistant, and breathable, paired with a rubber outsole and PU mudguard for durability. Insulation comes from PrimaLoft Gold with Cross Core (which incorporates Aerogel) and a 200g fill level, while a memory-foam plus EVA insole provides underfoot comfort.
• How should I size the Outdoor Research Women's Tundra Trax Slip-On Booties for the best fit?

  Customers report the Tundra Trax can run a bit small or narrow, so consider sizing up if you’re between sizes or plan to wear thick socks. Because it’s a slip‑on design, account for the ease of entry and your preferred sock thickness when choosing size to ensure comfortable toe room and ankle clearance.
• What does PrimaLoft Gold with Cross Core and Aerogel do for warmth and performance in wet conditions?

  PrimaLoft Gold provides high-loft synthetic insulation that retains warmth, and Cross Core integrates Aerogel particles to boost thermal resistance without much bulk. That combination helps the insulation maintain heat even when exposed to damp conditions, delivering lighter-weight warmth compared with traditional bulky fills.
• Are the Tundra Trax Slip‑On Booties good for icy or slippery surfaces and outdoor use?

  Yes, the booties have a rubber outsole with a PU mudguard that improves grip on icy or wet surfaces and shields the upper in muddy or rocky conditions. They’re best suited for winter camping, après-ski lounging, and casual outdoor use rather than technical mountaineering or long snow‑packed approaches.
