General Product FAQ

1.What is Callus Performance, and how do I use it?

Callus Performance® is designed by athletes for athletes; we have assured its design will prevent the ripping of your hand by strengthening the callus area to be able to continue your regular workout routine. Callus Performance® works in two easy ways: by trimming and by shaving the calluses; this will level the calluses with the rest of your hands by carefully removing excess skin.

2. Is it easy to cut yourself with this?

No, if instructions are followed it is the safest tool to remove the calluses. You can use the blade for trimming and shaving the extra build up or as much as needed, then switch to the other side and use the Emery Cloth sandpaper to smoothen it.

3. Can this be used on your feet or only hands?

Yes, you can use it on your feet like the way you use it on your hands. Use the blade for trimming and shaving, then switch to the other side and use the Emery Cloth sandpaper to smoothen the area. A lot of runners use it for their feet.

4. Does this product weaken the skin?

No, this product will not weaken the skin, but it’ll help in keeping the callus from ripping and causing painful irritation and bleeding.

5. Will this work for a gymnast?

Absolutely, the product is designed by athletes for athletes and can be used before or after any activity, which requires continuous friction of the hands such as Gymnastics, Climbing and Weightlifting.
