I think this is a great every day running shoe. I run about 35 miles/week and use this for all my longer runs.  One note is that this model is a little bit smaller than the Nimbus. I am 9.5 in the Nimbus but for Cumulus I need 10.  Edit: after 1 month a hole had formed in the padding for the heel and this caused the show to give me terrible blisters on the heel. I must say I am disappointed with the durability of a shoe that starts falling apart after only about 100-150 miles of running.
