Foot pain with cleated shoes I have cleated shoes. My feet do a lot of work floor miles and get I pain in ball of my foot. I feel like the cleat is pushing on the ball of my foot. 

I was considering changing the shoe liner; would this help or not? I have N.W foot wear, they are at least 6 month old.
Usually shoes for walking/running and cycling shoes are constructed quite differently: shoes you walk on are usually far less rigid, most have a much softer sole to absorb shocks/bumps, and of course do not have cleats. 

As this is ergonomics and people are quite different, there is probably no general answer: I find walking in SPD Trecking shoes uncomfortable, but not enough that I would not use them every day.

For your specific problem, I guess changing liners could help. However you'd need very stiff liners that actually distribute unevenness. I have not yet seen those.

Assuming you have static workplace: maybe you could arrange having a second pair of shoes specifically for walking there?
