Over 2-3 times a week and get to about 500 km / year. After about 2-2.5 years, you realize that the attenuation decreases and it's time for a new running shoe. The NIMBUS hold due to the higher quality material here usually half a year longer by.
Respect. the shoe size you should try ASICS before buying. I have in "normal" shoes usually a 42, what then is at ASICS 43.5.
I can recommend the series and CUMULUS NIMBUS without restrictions on its own Erfahreung!
