Delphin THERM are an electric heated insoles that will keep your feet warm even when it’s freezing outside. A universal size 40-46 will fit almost every shoe. After plugging the soles via USB into a power bank or another source of electricity (we don’t recommend connecting the soles directly into the mains), they can heat the inside of your shoes up to 40-45 °C. You’ll surely appreciate it during winter fishing sessions when staying long time in one place. For better comfort, they are made from very soft material. The soles can’t get in contact with water. If the soles are plugged in, we recommend careful manipulation.
