The Japanese archipelago, which is covered with the cold of midwinter this week, is cold anyway! Especially with sneakers with thin soles, even if you wear thick socks, you can't prevent the creeping cold.

So I tried the insole "warm sole" series that I found at the 100-yen shop "Daiso". Various materials such as boa, fur, and felt are available according to the heat generation level and the type of shoes.


There are two sizes, one for women (22 to 25 cm) and one for men (24 to 27 cm), both of which come with a guide and paper pattern that can be cut according to the size of the shoes. If a woman with big legs (I'm 25 cm) is uncertain about the size, I wonder if it's better to buy one for men.



Immediately put in the insole of the bore and it feels fluffy and comfortable as if you were walking on the carpet! As I walked, my legs naturally warmed up.


Also, if you want a higher level of protection against the cold, we definitely recommend the "Sunburner" material. It is a moisture-absorbing heat-generating material that generates about three times as much "heat of adsorption" as wool, so you can feel the soles of your feet warm even when you are still.


Of course, the price is 100 yen each (excluding tax), so why don't you feel free to incorporate it as a one-season item? In addition, adding an insole will make your shoes a little narrower, so if you feel it is too tight, don't force it on.
