Use a boot-calf stretcher to widen the calves of your leather boots. Buy 2 boot stretchers so you will have one for each boot. Insert the boot stretcher while it is unexpanded. Expand the boot stretcher until you see resistance in the leather. Leave the boot stretcher in place overnight for 6-8 hours."
article: There are a few different types of stretchers, and it's important to pick the right kind based on how your boots need to be stretched. If your boots are too narrow but otherwise fit great, you can use a 1-way stretcher to make the soles wider. Many shoe stores sell boot stretchers and you can also find them online. They generally cost about $20-$40. Boot stretchers can increase your boot size by 1/2-1 size total. If your boots are 2 sizes too small, though, you may need to buy a new pair. When you turn the handle on a 2-way stretcher, it both expands and elongates your boots. If your shoes are too narrow and if your heels or toes are consistently getting pinched or blistered, this is a great option for you. Wooden stretchers are the most durable option and add a nice scent to your boots, whereas plastic stretchers are less expensive and easier to travel with. Check out the reviews of different options when you go to make your purchase. You can buy a boot-calf stretcher on its own, or you can get one that is combined with a 1- or 2-way stretcher to adjust the fit of the entire boot at once. If just the calves of your boots are a little too tight, use a boot-calf stretcher on its own. These instruments are great for both hiking boots and zip-up or slip-on boots. There are even stretchers that will specifically target the instep of a boot in case that area is too tight for comfort. Most boot stretchers are sold in pairs, but some sources sell them individually. If you're ordering online, make sure to check and see if you'll be getting 1 or 2 stretchers with your order. If you aren't in a rush, you could purchase a single stretcher and use it over a few days and stretch each boot individually. You must get the stretcher into place in the boot first before you make any sizing adjustments. Slide the stretcher into the boot as far as it will go so that the tip of the toes fits snuggly into the end of the boot. You'll use the same process for a 1-way or 2-way stretcher. If you're using a calf stretcher on its own, you just need to put the stretcher down into the calf section of the boot. It shouldn't go into the actual sole section at all. Turn the handle clockwise to start the stretching process. Continue turning the handle until you see from the outside that the leather is being stretched. The handle will adjust both the width and the length of the stretcher if you're using a 2-way stretcher. If you're worried about over-stretching your boots, apply a light amount of pressure and then increase the amount of stretch each subsequent night until you get to the desired size. If you leave the stretcher in place for less time than this, it won't have much of an effect. It's also totally fine for you to leave the stretcher in place for longer periods. Depending on how much your boots need to be stretched, it may take 2-3 nights to get them to the right size. Be patient and try the boots on every morning to see how much progress has been made.

Write an article based on this "Calculate fuel costs by writing down the number of miles or kilometers on the odometer when the fuel tank is nearly empty. Fill the tank when it is near empty. Refill the tank when it is near empty again and write down the number of gallons or liters it took to fill. Check the odometer again at refilling and subtract the old number on the odometer from the new number to see how far you drove. Divide the number of miles or kilometers you drove by the number of gallons or liters it took to refill your tank. Divide the distance driven in a month by the miles or kilometers per gallon or liter. Multiply the total amount of fuel per month you burn by the cost of a gallon or liter of gasoline to get your monthly fuel costs."

Do not top off the tank. Do not top off when refilling. Write down the difference between the two odometer readings. If the number was 30,000 miles (48,280 km) when you filled the tank the first time and 30,300 (48,763 km) when you refilled, you drove 300 miles (482.8 km) on 1 tank of gas. For example, if you drove 300 miles (482.8 km) and burned 15 gallons (56.78 liters) of gasoline, your vehicle got about 20 miles per gallon (8.5 km per liter). (If your car has 30,000 miles [48,280 km] and is 40 months old, you drive about 750 miles [1,207 km] per month.) In this hypothetical example, divide 750 (1,207 km) by 20 gallons (75.7 liters) to get the number of gallons or liters you burn per month: 37.5 gallons (142 liters). If gas costs $4 per gallon ($1.05 per liter), you spend $128 per month on fuel, or 17 cents per mile (10 cents per km).
