Get Around

Since "get around" means "walk", footwear is one of the most important aspects of backpacking. Traditional hiking boots could kill a small animal just by being dropped on them (empty) from a few feet up, but modern boots can be much lighter, reducing the drag on every step you take. You don't necessarily need to spend hundreds of dollars on state of the art boots, but odds are your favorite athletic shoes or street shoes will leave you very uncomfortable and hold up just as poorly. Stiff soles and plenty of ankle support are a good idea if you're going over any rocks.

But buying a new pair of boots just before your trip is an equally bad idea. Break the boots in, first with short walks, then longer ones. Wear them around for a week, and you'll know where they rub, if you want to put soft insoles in them, etc. They should conform to the shape of your foot, so by the time you're ready to hike, your boots are too. The break-in period also helps your feet get used to the boots, building up thin callouses in the spots where they rub a little.

If the terrain is especially challenging, or if your knees aren't what they used to be, you might benefit from using a hiking stick or a pair of trekking poles (like cross-country ski poles, but without the skis). They aren't just for the feeble; they can improve your balance and increase your pace by adding some power from your arms to your propulsion. A sturdy chest-high branch (not pulled from a standing tree) will do, or you can buy a telescoping staff or set of poles. Some of them can double as a camera monopod. And while this usage isn't recommended, you'd probably rather face an angry cougar with a pole in your hand than without one.

Wear

The kind and quantity of clothing to wear depends heavily on the location and season. The key strategy in all but the hottest climates is to layer your clothing. If the temperature is going to vary between night and day (and it probably will), carrying a set of clothing for the warm times and another set for the cool times will take up extra space and add extra weight. Instead bring clothes cool enough for daytime hiking, and bring extra layers to put on over them when it cools off after dark. "Convertible" slacks are handy in warmer weather, allowing you to zip off the legs and turn them into shorts when the day gets warm, or back into long pants for wading through prickly plants.

Packing at least one complete change of clothes ensures that if any item you're wearing gets soaked (by rain, a misstep crossing a stream, sweat, whatever) you'll have another to wear instead. This is especially important for socks, which are both the most likely item of clothing to get wet and the most important to keep dry. Spare boots aren't practical, but a pair of cheap flip-flops or loose-fitting light-weight shoes will give your feet a chance to breathe when you're not on the trail, and give you something to wear after you accidentally dunk your foot in a pond while collecting water.

Although cotton is normally comfy, park rangers call it "death cloth". It soaks up water many times its weight and hence its drying time is very slow, making it a less-than-ideal choice for undershirts and underwear you'll be wearing next to your sweaty skin; synthetic fabrics such as capilene will "wick" moisture away from your skin, and can better keep you both cool and dry. Many discount stores will also sell suitable shirts in their sports department if you don't want to drop the money on the specialty brands. Cotton also doesn't keep you warm when it gets wet; wool is a better material for your socks and outerwear. Cotton t-shirts as a middle layer or for sleeping in are fine.

Do with this information what you wish: Humans in many cultures across countless centuries have lived without freshly laundered underwear every morning. Also, keep in mind that the kind of underwear you normally wear may not be ideal for backpacking; women will probably prefer a "sport" bra that provides more support and no hooks in the back, and men may find that briefs provide less opportunity for skin-to-skin chafing and bunched up fabric than boxers.

Eat

You'll want "light" meals, not in the sense of fat or calorie content, but in terms of how much the food weighs in your pack. In fact, you may want to lay off a lot of your "healthy diet" habits for the duration of your trip, because you'll want those extra calories, and fats are a good compact source of all-day energy.

• Breakfast -Oatmeal is a good option: inexpensive, lightweight to carry, and easy to prepare. Measure portions ahead of time into zipper-sealed baggies for more convenience. Add a spoonful or two of brown sugar to make it more tasty.
• Lunch -You might welcome lunch as an excuse to stop to eat during the day, but preparing food on the trail can be a nuisance, so on-the-go foods like trail mix, granola or energy bars, or peanut butter are handy. For short trips, or for the first day or two of longer trips, you can bring semi-perishable foods such as fresh fruit or bagels.

Drink

Be prepared to drink more fluids than you're used to. The reason overweight people sweat more than thinner people isn't just because they're well-insulated; it's because they're carrying around extra weight... just like a backpacker. If you're at your ideal body weight but carrying a 40-pound pack, expect to sweat like someone 40 pounds overweight. Walking for miles through the hills.
