I keep seeing this, and it's simply not true. airair did mine, and it just requires you to make the semi circles a few mm smaller than the originals. I also used cavxs clear soles, which tend to protrude a little from the soles which gives it room to flex. There is no reason that EL panels should break if done correctly. However, I would suggest adding sturdy insoles, followed by a soft one on top. This stops the shoes from flexing in the middle, causing the small bridge to snap. It's really quite simple logic.
Alternatively, add the EL panels as two separate pieces instead of the bridge and black tape.
In my case, it was not the EL panels that failed. It was the wires that passed through between two layers of fabric (I did my wiring so there was no holes inside the shoes) that rubbed as I walked and wore off the insulation. The bare copper shorted and that meant the EL did not light up.
I also did two parts for the sole instead of one because one won't flex enough when you walk. Didn't help the wires any.
