Well for starters, Welcome to Trailspace! Glad to see new members. Trailspace is a wonderful resouce of people and information.
Ok footwear. That seems to be the main question for a backpacker, and realistically it comes down to your own personal preference. You need a boot/shoe that fits you well, is comfortable, and meets your needs/expectations. That being said, what fits me well might not fit you well as everyones feet are different.
In regards to frequent or major river crossings and footwear there seem to be 3 distinct schools of thought on the matter. 1)just trudge through in your boots, 2) Take off your boots and put on water crossing shoes, 3) Take off boots and just go barefoot or sock only and trudge on through.
I tend to just trudge through if I am wearing my trail runners, however if I have my nice zamerlan leather boots on I will stop and take them off if I know I will be getting wet as they can take a while to completely dry.
So my advice on footwear would be one of these two options 1) buy a pair of trail runners or mesh boots 2) Buy a nice leather or waterproof hiking boot and also buy a cheapo pair of crocs, water shoes etc to cross water in. I personally like the water shoes as they are cheap, light, and stay on about 1000x better than crocs. Bottom line is find something that fits you well and ios comfortable and dont focus so much on the water crossing part.
Water crossings: This is a very important subject.
Water crossings can be fun, challenging, dangerous, or even down right deadly. It is esential that you weigh your options and evaluate the risks before attempting a major water crossing.
Some basic things to consider before ever entering the water.
1)Where to cross? You want to find the shallowest, slowest moving section.
2)Hazards in the water? Are there any downed trees, rapids, etc downstream from your potential crossing point. If you lose your footing and get swept down stream you don't want to get caught in debris than can pull you under or otherwise trap you.
3) What is your escape/bail point? If something goes wrong during the crossing what point on the bank are you going to shoot for, and what obstacles are there.
After you answer those questions its time to prepare yourself for a crossing. 1)If your going to be crossing in your boots then take out the insoles, this will allow them to dry much faster afterwards.
2) Ideally pack the inside of your pack with a dry bag or a liner that is sealed well at the top so that your pack will float.
3)Loosen all straps on your pack, and unbuckle the hipbelt and sternum strap. If you have to bail or get knocked over it is dramatically easier to get out of your pack this way and may save your life.
4) Wear sunglasses, they will allow you to better see into the water to spot potential hazards.
5) Face upstream when at all possible.
6) Use a treking pole etc to assit with balance while crossing
7) Securely plant one foot before moving the next while in the water.
OK, so you have evaluated the crossing, and its not going to be a crossing its going to be a swim. This is extremely dangerous if you don't know what your doing. Have you ever tried to swim with clothing on, boots on, not to mention a pack? Its extremely difficult even without a pack. I highly recommend taking off all clothing and footwear(if not aqua shoes) if your going to have to swim it. If you packed your pack so that it floats this will become much easier. A trick we learned in the military was to use your pack like a buoy and place it in front of you in the water, put your arms and upper chest on it and jsut use your legs to kick. It is best to swim at an angle downstream towards the opposite bank, a 45deg angle or so is fine.
Ok, so you cant figure out how to pack your pack so that it floats. Is the opposite bank close enough at any point where you can throw your pack across? Or throw a rope across? No? Well, STOP, because you will probably drown trying to proceed further.
And lastly NEVER TIE A ROPE TO YOUR BODY FOR ANY REASON DURING A CROSSING. It is ok to hold a rope in your hand only.
Hope some of this helps, and I'm not trying to be the party pooper, but it really can be a dangerous situation.
