I've been a Cumulus user since the 18. I'm a bigger runner (6'2", 195) so this shoe has been a little easier on my feet, knees, and hips. The 24, however, is disappointing. After using this shoe for a few weeks the left side of my foot began falling asleep during runs. Eventually a pain began to develop in my left knee and hip. Believe it or not, the pain eventually worked its way up to my shoulder. Thinking it may be the shoe, I switched back to my 23s for running. After switching back to my 23s (even with worn tread) the issues went away. I am done using the 24. I don't know if I will use them for everyday use. I'm seeing similar reviews on other sites citing a narrow toe box. So if this is design change related I might find another shoe. To spend good money on a shoe to protect your feet, legs, and hips just to have it do the opposite is disappointing.
