What is Ashiatsu? Is it similar to Shiatsu?

Ashiatsu, sometimes referred to as barefoot massage, encompasses massage forms in which the practitioner uses their feet more than their hands to deliver therapeutic pressure along the receiver’s body to promote health and well-being.

Ashiatsu literally translated means foot (ashi) pressure (atsu) in Japanese.
And Shiatsu is finger (shi) pressure (atsu).
