I tend to avoid changing shoes, but it depends on you. In not-totally freezing weather, I don't personally mind much hiking in wet feet. You may be different. I know some people who religiously change every crossing.

The other alternative, is not to change, but wear something lighter that will dry quickly,
such as a trail runner, or even a high tech sandal.

I personally don't have much problem just wading through in my boots and keeping going.. Of course, I've been on some wet ones - here I am below on the trail. and note. that's actually a trail, not a stream crossing....... At least, there usually isn't a stream going down that trail...
