I recently switched to a pair of Inov-8 Flyrocs after using Salomon Tech-Amphibs for over a year. The Tech-Amphibs really spoiled me in terms of how fast they dry. I could splash through a creek and have dry socks in about a mile on warm days. The Flyrocs, while super comfortable, do hold onto water much more, since they are a real shoe.

My personal preference is to spend the time I would use changing shoes to just look for an easier spot to cross, and if that's not possible, to just splash on through. The key is to wear train runners, or something not waterproof, and a good pair of socks that dry quickly. Synthetic or wool work, though my preference is wool, cotton is a poor choice.

After the first couple of times my waterproof boots turned into buckets I decided I would be much happier wearing something that let the water out once it got in. Bringing along an dedicated pair of 'dry' socks makes life a little more comfortable in camp as well.
