Good, up to about 2 hours
These shoes are awesome for commuting, spin class, and short MTB rides. They're comfortable, wide, and reasonably stiff. They're not so awesome once you pass the two hour mark. After that, they seem to head downhill, fast. The thin insole takes its toll on your feet, and you start to feel the recesses in the plastic underneath. Awhile later, you feel the bolt holes for your cleats, and by the time you're at around 4 hours, everything hurts.
Basically, these are badass entry-level shoes, but if you ride a lot, you'll want something a little nicer.
