Fieldsheer Mobile Warming Pro Compression Heated Socks – 3.7V, Bluetooth Control

Warmth engineered for winter athletes

When cold air bites at the edge of your ascent, Fieldsheer Mobile Warming Pro Compression Heated Socks provide targeted warmth where it matters most. Designed for ski boots and other snug-fitting footwear, these socks blend a snug compression fit with heating zones that sit above and below the toes, helping maintain comfortable warmth and steady circulation in demanding conditions. A modern, lightweight battery powers the system, and you can fine-tune heat right from your phone or smartwatch for flexible comfort during long days on the snow.

How warmth is distributed

Strategic heat placement under and over the toes helps create a consistent warmth profile where your feet tend to feel the cold first. The calf-length design with compression in key areas supports foot stability and overall snugness without adding bulk inside tight boots. A flat wire construction keeps the interior smooth for a comfortable ride, while reinforced heel and toe extensions add durability for repeated wear.

Smart control at your fingertips

Control and monitor your warmth via the MW Connect App, with Bluetooth wireless connectivity that also works with Apple WatchOS and WearOS. You can adjust temperature levels, check battery status, and tailor heat to your activity—whether you’re carving down a run or strolling between runs—without pulling off a boot.

Real-world use and maintenance

These socks shine on lift lines and in cold chair rides, especially in tight boots where extra warmth can help you stay focused on the activity. The moisture-wicking inner layer keeps feet drier, while odor control helps keep gear fresher between washes. When it’s time to recharge, a standard USB-C cable gets you back in action after a 5–6 hour charge, and the kit includes two socks plus two Powersheer batteries for ready-to-go warmth.

Note: While warmth can enhance comfort in cold conditions, results depend on environment and activity. The product is designed to complement winter sports gear and daily cold-weather use, not to guarantee outcomes.
