The ASA profile features a sculpted design with a slightly concave top and a curved shape that follows the natural curvature of the fingers. The height of the keys varies depending on the row, with the highest keys in the center and the lowest keys on the edges. This sculpted design helps to reduce finger strain and fatigue during long typing sessions.

The ASA keycap profile is compatible with Cherry MX-style switches and is available in a wide range of colors and designs. It is especially popular among keyboard enthusiasts who appreciate the high level of customization and the unique typing experience that it provides. While it is not as widely used as some of the more established keycap profiles like OEM and Cherry, it has gained a devoted following among those who appreciate its unique design and functionality.
