Electric Slippers Review: Working from Home in Winter, Invest in Your Feet

Hi there :) I’m a systems engineer in Tokyo. Work keeps me busy, so I’m always looking for small ways to make everyday life a little lighter.

Working from home in winter, have you ever had cold feet wreck your focus? Even with the heater on, my feet were always freezing.
These days, cordless electric slippers that warm up with a power bank are my winter sidekick.

Working from home in winter? For the sake of your focus, invest in something warm.

Cold feet, no work done

With just the air conditioner on heat, the room warms up, but my feet stay cold. And when my feet are cold, I just can’t focus on work.
That’s when I saw Kazuyo Katsuma, a Japanese economic commentator, recommend electric slippers, and I gave them a try.

Toasty feet, toasty everything

Just warming my feet makes my whole body feel pretty toasty. It cuts heating costs, too. I’m guessing it costs way less than heating the room with the air conditioner.

The power comes from a power bank in the slipper’s pocket. No cord, so I can walk anywhere in the house just as I am. Three heat levels at the push of a button. Even without the power on, they’re pretty cozy, and soft and fluffy inside.

Non-slip soles, easy to walk in. And they’re cute. In winter, they go everywhere in the house with me.

Six power banks, charged in turns

We have a charging spot just for the slippers.

When a power bank runs out, I swap it for a charged one at the charging spot, and the one I was using goes on to charge. Counting my husband’s and the replacements, we’re up to six chargers. We charge them in turn, so the slippers are always warm when I put them on.

I liked them so much that I gave one pair each to my husband and my mom. My husband works from home a lot too, and he doesn’t usually get cold feet, but he’s always swapping power banks and using them.

I broke them in the washing machine, and bought them again

To be honest, my first pair broke. I’m pretty sure it was my fault: I was too lazy to be careful and just tossed them in the washing machine…
The product page for my current pair says that if you take out the power bank and cover the charging port, you can wash them in the machine or by hand. But since I broke the first pair, I’m planning to wash them by hand from now on.

I still bought a second pair, because I felt I really needed them to keep my focus while working from home.
