It really does help.
Was sceptical but ordered anyway.  Glad I did.  Have a spot on the back of one heel that gets sore easily, don't know why, no bone spur.  This product does help with that.  It doesn't last (for me) much longer than it takes to get through the supermarket but it's small enough to carry in my handbag so if needed, just apply again.  etc.  All in all, I would buy again and recommend.  It really does help.
