I did something a little more primitive on my basement steps. I moved every tread out 1.5 inches (also used 3 1/2 inch deck screws)and put a piece of 2X behind it. It doesn't make the rise any better, but when you traverse the stairs, you have more tread width. I was at a friends over the holidays and nearly fell down the basement stairs several times. They were carpeted with a waterfall style and your heal would drag so much on the riser you would wind up on you tip toes on each tread. I would have changed my rise and treads, but the way my stairs come down they end facing a wall. There wasn't enough room there to maintain a decent space at the bottom.
