Anyone with more then one active pair of running shoes?

I recently got a hoka one one clifton 3 for rm400, from a friend that runs a shoe shop, he said it's good bla bla so i just got it since he's a friend.

I still have my first running shoe, gel nimbus 17 with 350km on it - i don't think it's even nearing the end of his life yet...

Do i
1. retire the asics
2. wear both on alternate days? Will it cause any problem? ie.leg/feet not used to the dynamics/shape of these shoes etc?

background info if it matters: started running around 3 months ago, pace according to strava is 4:50-5:10/km for the last 3 events that i joined, road2marathon/GE 12k/ score 15k.

thanks for the feedback, i will go ahead with training with hoka, and doing events with the more punishing asics.

whats the weight of you runners here in this thread? Is 80kg too heavy to run? ie. more damaging to bones etc?

most of the people that i personally know who's into running is not reaching 70, or barely above 70...
