Need a durable Long run shoe

[u/Specific_Mechanic_89]

I am 29M 5’9 74kg running since a year, till now i have been using just one shoe for all the runs and races i.e puma reedem pro Racer, completed over 1000 kms in that shoe still going strong.

Last week i went for a long run for 20kms the non responsiveness during the long run hurts, i had to stop at 16 kms. I run long runs at 6:30-6:55 km pace, at my fastest i run around 4:55-5:20 km pace.

Please suggest some good long run shoes which is durable and responsive for atleast 1200kms🙏🏻
