Electric foot care roller with USB battery | Kalsten
Cracked heels that run through every sock – and no end in sight.
The reach for the file often ends in frustration: too little pressure, too little time, no visible results. The electric callus remover from Kalsten rotates through dead skin layers in seconds, leaving soles that feel soft and smooth again – without scrubbing, without effort. Just turn it on, apply it, and you’re done.

Benefits
- No more tired hands after foot care: A single button press starts the device – you just guide it, the device does the work by itself.
- No interruptions in the routine: The 450 mAh battery lasts up to 6 hours and is fully charged again after 4 hours – you always reach for a ready-to-use device.
- No nasty surprises from overheating or blockage: The automatic shut-off function detects critical conditions and stops the device before anything happens – you don’t have to monitor anything.

Specifications
- Battery: 450 mAh, rechargeable via USB
- Charging time: approx. 4 hours
- Usage duration: up to 6 hours
- Display: LCD display for battery level and speed
- Safety: Automatic shut-off in case of overheating or blockage
- Color: Available in Orange, Blue, or Gray

Application
- Charging: Fully charge the device via USB before first use, until the LCD shows 100%.
- Apply: Place the grinding attachment on the affected area of the sole or heel and turn on the device.
- Guide evenly: Move the device in slow circular motions over the callus until the skin feels soft – the LCD displays battery level and speed live.
Pro tip: Massage the skin with a moisturizer immediately after treatment – the freshly removed layer absorbs care particularly well at this moment, and the results last noticeably longer.
