I've based myself near Cortina d'Ampezzo before, for routes on Marmolada and nearby.
You do need to have a Kinetic Impact Shock Absorber to hook your harness to the Via Ferrata.
Something like this:

They are to protect the via ferrata as much as you!
The Via Ferrata is generally in poor condition, and a full impact fall can unzip it from the crumbling rock.
They also have two tails, so you can clip in one above an anchor point before un-clipping the lower one; so you are never unprotected.
The Dolomite is water-soluble, and is dissolving away day by day.
Expect lumps of it to come away in your hands.
Big friendly flakes to pull up on can come away in your hands and land on your head!
The high-traffic routes along the lines of the via ferrata ( esp. on Marmolada ) are *very highly* polished, and can be tricky going.
Watch out for the massive thunderstorms at 4pm every day!
