Out in the Cold: Testing the Lenz Heated Socks

I took the socks for a spin over a three-day ski trip in Colorado. Here's how they fared:

Warmth and Comfort

To my delight, the heating element worked like a charm. It kept my toes cozy even in sub-zero temperatures. The socks felt snug in my ski boots, with no bunching or discomfort.

Battery Performance

The battery packs were unobtrusive, but I did notice a slight imbalance in battery life. On high, they lasted closer to 6 hours instead of the advertised 14 hours, which required some mid-day management.

Heat Control

With the Lenz heat control app, adjusting the temperature was a breeze. The three heat settings provided a good range to find the right level of warmth.

Durability Test

After three days of rigorous skiing, the socks held up well. Though only time will tell their longevity, they seem robust enough to endure multiple seasons.
