S. Krantz & Son, 180 Drury Lane, Borough of Camden, Loncon WC2, 2003 • Still there, but downsized to Krantz, painted dark blue, and with the beautiful old signage – and surgical shoes mention – gone. Shops don’t boast “highly skilled staff” these days, do they? I wonder why…
Shopfront Elegy 
Brilliant artisans. They serviced footwear for the theatres, including ballet shoes. I had all of my ( often pricey footwear) repaired by them in the 80s when I worked in Neal Street. They did invisible sewing on leather and could literally bring your shoes back to new, using the best materials.
Even after I stopped working in Covent Garden, I still took my shoes to them. Good old days.
Thanks, I guessed it was a theatreland staple. So sad to see these things so.
