Shoe rotation or addiction?

With the shopping season upon us I am going to end up buying too many shoes, but I will always try to talk myself into a rational reason for needing them.

Some background I am a big guy 220lbs so I definitely feel the foam come back after giving it a few days in between vs wearing the same shoe every day. I usually go above 400 miles in my shoes most times reaching 500. I've had a 3-4 shoe rotation for a while and the brands change but this will be my current

Speed Runs - NB Rebel v4 ($55)

General Aerobic Runs - NB 1080 v14 ($75)

Recovery Runs - NB More v5 ($60)

Long Runs - Asics Gel-Nimbus 27 ($80)

Too much? What is your shoe rotation, and what has worked best for you?
