Heated Shoe Insoles

InFein rechargeable 3V heated insole is the answer to eliminating cold toes in up to 8 hours on a single charge! The integrated heating system under the toes is used in conjunction with a rechargeable 3-volt battery embedded in the heel. You no longer need to worry about the battery being placed in the wrong place or encountering problems during installation; Just charge the insoles, open them, and immediately feel the warmth! The convenient trimming contour on the insole guides you to customize the fit that suits your shoes, and the thin contour of the insole ensures a comfortable fit.
Whether you are working, playing, or just doing daily activities in the cold, inFein heated insoles allow you to control the temperature with the app, and 4 heat level settings allow you to easily adapt to various weather and environments. Wearing these heated insoles, your feet and toes won't feel cold anymore!

The adjustable shirt balloon is suitable for sizes below 3XL and can be easily adjusted using the side zipper - the more you open, the larger the balloon will be.
This three in one model allows you to iron tops such as shirts, t-shirts, and polo shirts, bottoms such as pants, and even use the included rack to quickly and effectively dry shoes.
