Therm-IC Powersocks Heat Fusion Uni Heated Socks with S-Pack 700B Bluetooth Battery

If you struggle with keeping your feet warm when out and about in winter, the Therm-IC Powersocks Heat Fusion Uni Heated Socks with S-Pack 700B Bluetooth Battery are an effective solution. Made with super-soft merino wool and featuring a heating element that radiates warmth around your feet, they offer lasting comfort, even on the coldest days. There are three heat settings to suit different weather conditions, which can be easily controlled from an app on your phone.

What's Included?

The following items are included:

Which Size Is Right for Me?

The Therm-IC Powersocks Heat Fusion Uni Heated Socks is available in four sizes based on shoe sizes. Use the table below to find the size that's right for you:

EU Shoe Sizes UK Shoe Sizes
Sizes 35 - 38 Sizes 2.5 - 5
Sizes 39 - 41 Sizes 5.5 - 7
Sizes 42 - 44 Sizes 8 - 9.5
Sizes 45 - 47 Sizes 10.5 - 12

Heat Transfer System

To ensure the heat the Powersocks provide is distributed evenly across your feet, the socks utilise a high-tech heat transfer system. This helps to ensure even circulation of heat across feet, preventing certain areas of the foot from being colder than others. There are even three different heat settings to help you get the warmth you want.

What's the Difference Between These Heat Fusion Socks the Uni Heated Socks?

The Uni Heated Socks feature a single heat pad under the toes, whereas these Heat Fusion Socks feature a heating element that's designed to disperse heat around the foot for more even coverage. In addition, these Heat Socks have micro channels to help wick away moisture and are made with merino wool for unrivalled comfort.

Up to Eight Hours of Battery Life

Ideal for all-day use, the included S-Pack 700B battery pack provides up to eight hours continual use with Therm-IC Powersocks. What's more, the pack takes between two to three hours to fully charge from flat. This is ideal for charging during the evening and getting them ready to go for the next day.

Three Heat Settings for Customised Warmth

To help you get the level of warmth your feet need, the S-Pack 700B features three heat levels – low, average and high. The battery life at each of these levels is:

  • Low: 6 - 8 hours
  • Medium: 3.2 - 4.25 hours
  • High: 2 - 2.5 hours

Bluetooth-Equipped for Remote Control from Your Phone

The Bluetooth connectivity in the battery enables you to control the socks using your smartphone. Available for iOS and Android, the app provides you with everything you need for full control of the socks, making it easy to adjust the heat level while on the move.

Compact Design

For those looking for a battery pack that won't get in the way of their activity, be it skiing or just walking to the shops, the S-Pack 700B features a slim and compact design. This keeps the socks discreet and unobtrusive, helping you go about your day much more easily.

USB Charger Included

For easy and simple recharging, the battery pack includes a USB charger. This simply plugs into a standard USB port and helps ensure you have an easily accessible way to charge your batteries. Please note that a wall mains charger is not included.

Merino Wool for Lasting Comfort

Combining merino wool and high-performance synthetic materials, the Heat Fusion socks offer lasting comfort, even with long-term wear. Not only are they soft and heat-retaining, they're also moisture-wicking to prevent the excess build-up of sweat.

Reinforced for Outdoor Activities

The heels and toes of socks are high-friction areas during outdoor activities like winter sports and manual labour. To compensate for this, these Therm-IC Socks have been reinforced for durability and to protect your feet.

Easy to Wash

The socks can be washed up to 30°C, making it incredibly easy to keep them fresh and ready to wear. The optimised positioning of the heating elements helps to improve the life of the socks further, keeping them protected and safe.
