If your feet have calluses that never seem to go away, no matter how many pedicures you get, you've gotta try this tool that I swear by to get rid of them.
This is probably TMI and I hate that it's my life, but I have the worst calluses that always keep coming back on the heels of my feet. I had religiously used my Amope electric file to attempt to get rid of them for years, but it seemed like no matter what, the calluses continued to grow despite my efforts.
But then I found this callus shaver by ZIZZON, and it's been a total game changer.
It's kind of intense, but hear me out...shaving calluses off your feet is the most effective way to get that gross dead skin off. I'm not a professional so I can't say it's the BEST way, but it's the only thing that's actually really worked for me.
The tool comes with replacement blades so you can always have a clean "shave" and stay as cleanly as possible. It's also super affordable.
Don't shave the skin while it's dry, otherwise you risk deep cuts. (I've tried it before and it's a terrible mistake to make.) Instead, gently shave the dead skin off after a shower or bath. The softer the skin, the easier it is to shave off and prevent cuts. It gets MOST skin off, but you'll most likely need to use a file to buff away the rest, or just go get a pedicure to smooth things out.
The one I got was from Amazon, and it's Prime eligible. Get the info here.
