When I suddenly notice it, my feet are cold in winter. Moreover, once it gets cold, it doesn't get warm, so it's really unreasonable.
I've tried using winter slippers, but it's not good because it's difficult to put on and take off or walk. At that time, I found this "foot warmer" at the 100-yen shop Daiso. It's a 400 yen product, but I bought it because of its big size of 31 x 31 cm and its cuteness.
It is like a cushion with an animal face as a motif, and has a slit in the back to insert the toes. The fluffy and fluffy texture feels good.
I can't say that my cold feet warm up in an instant because they don't generate heat, but they gradually warm up as I put them in. Also, if you put it in while your feet are warm, such as after taking a bath, it will protect you from the cold.
It is best to set it at the foot of the chair and use it when sitting and working. You can put it in a futon and use it to warm your feet before going to bed. A foot warmer that usually serves as a cushion, for those who are worried about cold feet, why not try it.
