As the sign over the shop says Gould Bros, I think it likely (in fact almost certain) that the entry in Kellys will be Gould Bros.
Gould Bros are listed in Kellys at 211 Coventry Road, bootmakers, from about 1888 (not there 1884) till sometime after 1921
Also from 1904 till about 1908 (not there 1910) they were also at 401 Stratford Road listed as boot repairers .
The map below shows no 211 (numbering around here was altered around 1884, but not between then and 1950)
It is difficult to tell if this might be the building in th ephoto. If the view was slightly wider then it would be easy
