So I recently dropped off my pair of Edward Green Chelseas to have steel toe taps installed by a reputable shoe repair company in NYC. I've had them do all the my toe taps in the past and I have nothing but praise for them. But my latest pair of shoes came back with an issue. After wearing the shoes for an hour I noticed the the sole on the left shoe had developed a crack. Inspecting further, the crack goes through the entire sole: Now judging by the vicinity to the toe tap installation, I can only deduce it was caused by that. Is this something to worry about? The crack actually moves like tectonic plates when I walk on it. I feel this crack has compromised the integrity of my sole and might require a resoling prematurely. Should I bring this up with the shoe repair store? Has anyone seen this before?
