Mark Sensenbach perches on a stool, back slightly hunched, eyes down, brows narrowed in concentration. His hands, toughened by mountains and work, maneuver the rubber sole of a climbing shoe against a sanding wheel.
His movements made smooth by practice, Mark runs the shoe back and forth, rotates and repeats. He draws it away from the wheel for a moment and thumbs around the edges of the shoe, feeling for imperfections. There must have been a few, because the shoe goes back to the wheel once again.
Mark looks up and smiles. “That’s pretty much how it goes in here,” he says, gesturing around his workshop.
