I was part of a rescue of a climber with a broken foot in Tuolumne meadows. The guy was about 600 feet up on terrain about 5.4 and probably a lot like the terrain near the cables. I just climbed up it walking erect in my climbing shoes. The guys partner and I got on either side of him and walked him down facing away from the rock. He hopped so we had 5 feet on the rock. It wasn't back but we were all experienced friction climbers. A ranger rescue team met us at eh bottom of the technical rock.
At 5.4 I could probably just walk up and down without the cables, I thought it was a lot more severe there. Tennis shoes - you would "butter", that is there would be no stopping or turning around.
