It's tagged as craft=shoemaker, and the default rendering style (OSM Carto) does not render that. 

The sign outside actually says "key cutting, shoe repairs" (no indication that they make shoes), so I've replaced the tag with "shop=shoe_repair" and "craft=key_cutter". Let me know if you disagree. A side effect of that the shop should start showing up on the map, because shop=shoe_repair is rendered.
