Columbia Men's Portland Omni-Heat Infinity Waterproof Winter Boot

The Portland shoes use Columbia’s Omni-Tech membrane to keep moisture out. The ankle-high design protects against wind and splashes.

Inside, the shoes feature the ingenious Omni-Heat Infinity lining. Originally developed for NASA, this material uses metallic elements to reflect your body’s radiant heat back. While the main warmth comes from the warm air trapped in the lining, this technology adds an extra touch of warmth.

• Waterproof construction
• Durable textile as the outer material
• Techlite midsole optimized for walking comfort with shock absorption
