HI everyone

I have a hard bit of skin between 2 toes and has been there for years. Is there anything I can do to get rid of it? I tried soaking, rubbing with a pumice stone, picking at it, using nail clippers, etc. It seems like dead skin, doesn't hurt to touch, but sometimes causes pressure between the toes and throbbing.
It seems to be below the skin just a bit. It is very annoying , but not a major problem. If anyone knows what i am talking about, please help!

Thanks
