Getting The Treads Down

I went with an engineered flooring for the treads.  3/8" x 4 3/4" random planks.  The flavor is Maple Sedona and the contrast between the Red Mahogany nosing proved to be excellent to my eye.  I put down an 1/8" foam under-layment, directly stapled to the plywood substrate.  I needed to make up an 1/8" inch to match the height of the nosing so it worked out perfectly.  The stairs feel solid under foot.
