I'm going to give the opposite reason to skip that shoe. They won't run well enough.
Most 'cross courses have a run-up. By the end of the season, these things get slick and loose. Toe spikes are very helpful - get a real MTB shoe, that has sockets for them. IME, there's no conflict between a good shoe for cycling and a good shoe for a run-up. That funny cycling last works quite well.
