Funny that you brought this up.
On several occasions I have had customers request them that didn't need them.
We always inspect the toe area to see if the sole has worn to far towards the welt. If that's the case it needs a leather build up before we can install the flush mounted toe pieces. Many times I see the toe area shows hardly any wear. I tell the customer you really don't need them (I can tell his gait from the wear pattern).
I figure I'll save the guy $40.00. I get the same reply, "I want them anyway, I like the way they look".
