Boston winters have no mercy on your sole. Thankfully, George Triantafillidis and his wife are your shoe saviors. Triantafillidis repairs broken-down heels, flats, lace-ups and loafers with a craftsmanship that he’s been honing since his teen years, which he spent assisting his dad in a similar repair shop in the Pru. Pick-up and delivery services are also available, should you find yourself ill-equipped to hoof it to the South End.
