The smell hits first as you descend the short flight of steps into the basement. It’s sharp and overpowering, a mix of rubber and old leather. This is where old shoes go to be reborn. The basement workshop in Tamas “Zen” Pomazi’s Waconia, Minn., home is filled with shoes: Red Wing work boots, wingtips and loafers overflow the shelf space and sprawl across the floor. Each aging shoe will go through the same process — Pomazi pulls them apart, then stitches them back together, and finally, outfits the bottom with an eye-popping custom-colored sole.
