Resolved the Broken Cleat Bolt on Sidi Shoes

The drill is screaming!

A customer left me with Sidi road shoes with a carbon sole.
The cleat bolt snapped cleanly at the front hole, and they asked me to do something about it.
Apparently the shop they usually go to turned them down,
but since that wasn't the shop that sold them the shoes originally, oh well.

It's broken flush with the surface.
Using a carbide drill that cuts through steel like butter

My plan to cut a slot for a mini screwdriver and turn it out didn't work.

Well, there's no helping it—with open excavation while keeping the center true (high difficulty when dealing with steel)
I managed to extract it

Switched tactics to installing a helicoil insert.
In the worst case I could just drill straight through,
but I managed to drill the hole without letting the drill tip touch the shoe's sole material.
How's that—pretty impressive, right! (giving myself a pat on the back)
