You'll see some benefit from going to a lighter/racing type shoe. You'll need to get some miles in them and get used to them. You need to weight if its worth taking a little bit more of a beating for that extra minute. Also I wouldn't wear Bostons or Adios to an elementary school sponsored 5k. Both are decent shoes but they are firm and heavy for what you get. Kinvara would be a better option in my opinion. Or hands-down VFs if you want to drop the cash.
Okay, if you think adios is too harsh for what it claims to be - a marathon racing flat, what do you think is a better alternative at the same price/class?
I'm assuming kinvara which you suggested is a boston alternative.
